Description Of Business	'
	1. Description of Business
	Stereotaxis designs, manufactures and markets the Epoch Solution, which is an advanced remote robotic navigation system for use in a hospital’s interventional surgical suite, or “interventional lab”, that we believe revolutionizes the treatment of arrhythmias and coronary artery disease by enabling enhanced safety, efficiency and efficacy for catheter-based, or interventional, procedures.  The Epoch Solution is comprised of the Niobe ES Robotic Magnetic Navigation System (“Niobe ES system”), Odyssey Information Management Solution (“Odyssey Solution”), and the Vdrive Robotic Navigation System (“Vdrive system”).
	The Niobe ES system is the latest generation of the Niobe Robotic Magnetic Navigation System (“Niobe system”), which is designed to enable physicians to complete more complex interventional procedures by providing image guided delivery of catheters and guidewires through the blood vessels and chambers of the heart to treatment sites. This is achieved using externally applied magnetic fields that govern the motion of the working tip of the catheter or guidewire, resulting in improved navigation, efficient procedures and reduced x-ray exposure.
	In addition to the Niobe system and its components, Stereotaxis also has developed the Odyssey Solution, which consolidates all lab information enabling doctors to focus on the patient for optimal procedure efficiency. The system also features a remote viewing and recording capability called the Odyssey Cinema solution, which is an innovative solution delivering synchronized content for optimized workflow, advanced care and improved productivity. This tool includes an archiving capability that allows clinicians to store and replay entire procedures or segments of procedures. This information can be accessed from locations throughout the hospital local area network and over the global Odyssey Network providing physicians with a tool for clinical collaboration, remote consultation and training.
	Our Vdrive system provides navigation and stability for diagnostic and therapeutic devices designed to improve interventional procedures. The Vdrive system complements the Niobe ES system control of therapeutic catheters for fully remote procedures and enables single-operator workflow and is sold as two options, the Vdrive system and the Vdrive Duo system. In addition to the Vdrive system and the Vdrive Duo system, we also manufacture and market various disposable components which can be manipulated by these systems.
	We promote the full Epoch Solution in a typical hospital implementation, subject to regulatory approvals or clearances. The full Epoch Solution implementation requires a hospital to agree to an upfront capital payment and recurring payments. The upfront capital payment typically includes equipment and installation charges. The recurring payments typically include disposable costs for each procedure, equipment service costs beyond warranty period, and software licenses. In hospitals where the full Epoch Solution has not been implemented, equipment upgrade or expansion can be implemented upon purchasing of the necessary upgrade or expansion.
	The core components of Stereotaxis systems have received regulatory clearance in the U.S., Europe, Canada and elsewhere.  The V-Sono ICE catheter manipulator has received U.S. clearance, and the V-Loop circular catheter manipulator is currently in clinical trials in order to obtain clearance by the U.S. Food and Drug Administration.
	Since our inception, we have generated significant losses. As of September 30, 2013 we had incurred cumulative net losses of approximately $449 million. In May 2011, the Company introduced the Niobe ES system. As of September 30, 2013, the Company had an installed base of 92 Niobe ES systems and has received positive feedback from the physicians at these sites.  During the third quarter of 2011, the Company implemented a wide ranging plan to rebalance and reduce operating expenses by 15%  to 20% on an annual run rate basis.  During the year ended December 31, 2012, the Company reduced operating expenses by approximately $19 million or 31% over the prior year.  We expect to incur additional losses throughout the remainder of 2013 as we continue the development and commercialization of our products, conduct our research and development activities and advance new products into clinical development from our existing research programs and fund additional sales and marketing initiatives.

Summary Of Significant Accounting Policies [Abstract]	'
Summary Of Significant Accounting Policies	'
	2. Summary of Significant Accounting Policies
	Basis of Presentation
	The accompanying unaudited financial statements of Stereotaxis, Inc. have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all the disclosures required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, they include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods presented. Operating results for the nine month period ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ended December 31, 2013 or for future operating periods.
	These interim financial statements and the related notes should be read in conjunction with the annual financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 as filed with the Securities and Exchange Commission (SEC) on April 1, 2013.
	As described in Note 10, on July 10, 2012, the Company effected a one-for-ten reverse stock split of the Company’s common stock. All information set forth in the financial statements and related notes gives effect to such reverse stock split.
	Financial Instruments
	The Company measures certain financial assets and liabilities at fair value on a recurring basis, including warrants and debt conversion features. General accounting principles for fair value measurement established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (“Level 1”) and the lowest priority to unobservable inputs (“Level 3”). See Note 11 for additional details.
	The following methods and assumptions were used by the Company in estimating its fair value disclosures for other financial instruments as of September 30, 2013 and December 31, 2012.
	Cash equivalents, accounts receivable, and accounts payable have carrying values which approximate fair value due to the short maturity or the financial nature of these instruments.
	Long and short-term debt fair value estimates are based on estimated borrowing rates to discount the cash flows to their present value. See Note 9 for disclosure of the fair value of debt.
	Revenue and Costs of Revenue
	For arrangements with multiple deliverables, the Company allocates the total revenue to each deliverable based on the provisions of general accounting principles for revenue recognition and multiple-deliverable revenue arrangements and recognizes revenue for each separate element as the criteria for revenue recognition are met. Each element is assigned an estimated selling price using vendor-specific objective evidence, third party evidence, or management’s estimate.
	Under our revenue recognition policy, a portion of revenue for the Niobe,  Odyssey Vision, Odyssey Cinema, and Vdrive systems is recognized upon delivery, provided that title has passed, there are no uncertainties regarding acceptance, persuasive evidence of an arrangement exists, the sales price is fixed and determinable, and collection of the related receivable is reasonably assured. Revenue for Niobe, Odyssey Vision Standard HD, Odyssey Vision Quad, Odyssey Cinema, and Vdrive systems is recognized upon delivery due to the fact that third parties became qualified to perform installations. Revenue is recognized for other types of Odyssey systems upon completion of installation, since there are no qualified third party installers. When installation is the responsibility of the customer, revenue from system sales is recognized upon shipment since these arrangements do not include an installation element or right of return privileges. The Company does not recognize revenue in situations in which inventory remains at a Stereotaxis warehouse or in situations in which title and risk of loss have not transferred to the customer. However, the Company may deliver systems to a non-hospital site at the customer’s request as outlined in the terms and conditions of the sales agreement, in which case the Company evaluates whether the substance of the transaction meets the delivery and performance requirements for revenue recognition under “bill and hold” guidance. Amounts collected prior to satisfying the above revenue recognition criteria are reflected as deferred revenue.
	Revenue from services and license fees, whether sold individually or as a separate unit of accounting in a multiple-deliverable arrangement, is deferred and amortized over the service or license fee period, which is typically one year. Revenue from services is derived primarily from the sale of annual product maintenance plans. We recognize revenue from disposable device sales or accessories upon shipment and establish an appropriate reserve for returns. The return reserve, which is applicable only to disposable devices, is estimated based on historical experience which is periodically reviewed and updated as necessary. In the past, changes in estimate have had only a de minimus effect on revenue recognized in the period. We believe that the estimate is not likely to change significantly in the future.
	Costs of systems revenue include direct product costs, installation labor and other costs, estimated warranty costs, and initial training and product maintenance costs. These costs are recorded at the time of sale. Costs of disposable revenue include direct product costs and estimated warranty costs and are recorded at the time of sale. Cost of revenue from services and license fees are recorded when incurred.
	Share-Based Compensation
	The Company accounts for its grants of stock options, stock appreciation rights, restricted shares, and restricted stock units and for its employee stock purchase plan in accordance with the provisions of general accounting principles for share-based payments. These accounting principles require the determination of the fair value of the share-based compensation at the grant date and the recognition of the related expense over the period in which the share-based compensation vests.
	The Company utilizes the Black-Scholes valuation model to determine the fair value of stock options and stock appreciation rights at the date of grant. The resulting compensation expense is recognized over the requisite service period, which is generally four years. Compensation expense is recognized only for those awards expected to vest, with forfeitures estimated based on the Company’s historical experience and future expectations. Restricted shares granted to employees are valued at the fair market value at the date of grant. The Company amortizes the fair market value to expense over the service period. If the shares are subject to performance objectives, the resulting compensation expense is amortized over the anticipated vesting period and is subject to adjustment based on the actual achievement of objectives.
	Net Loss per Common Share (“EPS”)
	Basic and diluted net loss per common share (“EPS”) is computed by dividing the net loss for the period by the weighted average number of common shares outstanding during the period.
	The following table sets forth the computation of basic and diluted EPS:
		Three months ended September 30,				Nine months ended September 30,
		2013		2012		2013		2012
	Numerator:
	Numerator for basic EPS	$	-56,868,442	$	-1,915,281	$	-64,795,382	$	-4,921,766
	Effect of dilutive securities:
	Subordinated convertible debentures		—		—		—		—
	Numerator for diluted EPS	$	-56,868,442	$	-1,915,281	$	-64,795,382	$	-4,921,766
	Denominator:
	Denominator for basic EPS—weighted average shares		12,666,414		7,701,332		9,640,249		6,651,255
	Effect of dilutive securities:
	Subordinated convertible debentures		—		—		—		—
	Denominator for diluted EPS		12,666,414		7,701,332		9,640,249		6,651,255
	Basic EPS	$	-4.49	$	-0.25	$	-6.72	$	-0.74
	Diluted EPS	$	-4.49	$	-0.25	$	-6.72	$	-0.74
	In addition, the Company did not include any portion of unearned restricted shares, outstanding options, stock appreciation rights or warrants in the calculation of diluted loss per common share because all such securities are anti-dilutive for the three and nine months ended September 30, 2013 and the three and nine months ended September 30, 2012. The application of the two-class method of computing earnings per share under general accounting principles for participating securities is not applicable during these periods because the Company’s unearned restricted shares do not contractually participate in its losses.
	As of September  30, 2013, the Company had 238,989 shares of common stock issuable upon the exercise of outstanding options and stock appreciation rights at a weighted average exercise price of $46.83 per share and 3,021,302 shares of common stock issuable upon the exercise of outstanding warrants at a weighted average exercise price of $14.30 per share. The Company had a weighted average of 25,657 and 36,135 unearned restricted shares outstanding for the three and nine months period ended September 30, 2013.
	Recently Issued Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU” or “Update”) 2013-02, “Comprehensive Income: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” which adds new disclosure requirements for items reclassified out of accumulated other comprehensive income (“AOCI”). The update requires that the Company present either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of AOCI based on its source and the income statement line items affected by the reclassification. The guidance is effective for interim and annual reporting periods beginning on or after December 15, 2012. As the Company has no items of other comprehensive income, the Company is not required to report accumulated other comprehensive income.
	In December 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2011-11, “Disclosures about Offsetting Assets and Liabilities.” The Update enhances the disclosure of offsetting assets and liabilities by requiring companies to disclose both the gross and net information about instruments and transactions eligible for offset as well as those subject to an agreement similar to master netting arrangements. This guidance is effective for the Company’s interim and annual periods beginning January 1, 2013. The adoption of this pronouncement did not have an impact on the financial statements.
	In June 2011, the FASB issued new accounting guidance related to the presentation of comprehensive income that increases comparability between U.S. GAAP and International Financial Reporting Standards (“IFRS”). This guidance eliminates the current option to report other comprehensive income (OCI) and its components in the statement of changes in stockholders’ equity and requires the presentation of a separate statement of comprehensive income. This guidance was effective for the Company’s interim and annual periods beginning January 1, 2012. As the Company has no items of other comprehensive income, the Company is not required to report comprehensive income or other comprehensive income.

	On June 4, 2010, the Company entered into an agreement to issue 45,000 shares of its common stock to a consultant (the “Purchaser”) in exchange for intellectual property rights related to the Company’s products. The Company issued 20,000 shares upon execution of the agreement and has issued an aggregate of 25,000 shares in annual installments on the first three anniversaries of the agreement. There was no cash consideration paid for the securities. The securities were issued in consideration of the assignment to the Company of the Purchaser’s rights in certain intellectual property, including patent applications, in all inventions and discoveries in the Company’s business field (as defined in the agreement) that had been developed under various other agreements, which were terminated. The securities were sold by the Company in a private placement exempt from registration under Section 4(2) of the Securities Act of 1933 and Regulation D promulgated thereunder. There were no underwriters or placement agents involved in the transaction.
	As of September 30, 2013, the Company had total intangible assets, including those described above, of $3,665,000. Accumulated amortization at September  30, 2013, was $1,910,555.

	In accordance with general accounting principles for fair value measurement, the Company’s debt and credit facilities were measured at fair value as of September 30, 2013 and December 31, 2012.  Long-term debt fair value estimates are based on estimated borrowing rates to discount the cash flows to their present value (Level 3).  The carrying amounts of the Subordinated Convertible Debentures are net of the respective unamortized debt discount as of December 31, 2012.
	Revolving line of credit
	In September 2011, the Company amended its agreement with its primary lender.  The amendment reduced the availability amount of all credit extensions, other than the term loan, from $30 million to $20 million, and modified the interest rate applicable to the term loan from the lender’s prime rate plus 3.5% to the lender’s prime rate plus 5.5%.
	On November 30, 2011, the Company entered into a Second Amended and Restated Loan and Security Agreement with its primary lender (“Amended Loan Agreement”). Under the Amended Loan Agreement, the Company agreed to revised tangible net worth and liquidity ratio covenants. Further, certain intellectual property assets of the Company were added to the collateral which secures repayment of the loan. Finally, the Amended Loan Agreement permits the Company to repay Healthcare Royalty Partners II, L.P. (“Healthcare Royalty Partners”), formerly “Cowen Healthcare Royalty Partners II, L.P.”, with the royalties due to the Company under the Biosense Agreement (the "Biosense Agreement"), as described below.
	On March 30, 2012, the Company amended its agreement with its primary lender.  The amendment extended the maturity date of the working capital line of credit from March 31, 2012 to April 30, 2012 and reduced the Company’s borrowing availability by $3,333,333.  The Company also received from stockholders, who at the time were affiliates of two members of our board of directors (the “Lenders”) and were considered to be related parties, an extension of their commitment to provide $10 million in loan guarantees until April 30, 2012.  As a result of this extension, the Company issued the Lenders warrants to purchase 75,735 shares of common stock at $6.60 per share.
	On May 1, 2012, the Company and its primary lender entered into an agreement in which the lender extended the maturity of the revolving line of credit from April 30, 2012 to May 15, 2012.  The Company and the Lenders also agreed to amend their agreement to extend the $10 million loan guarantee through May 15, 2012.  The Company granted warrants to purchase an aggregate of 60,976 shares of common stock at $4.10 per share in exchange for the extension of the guarantee.
	On May 10, 2012, upon closing of financing transactions for gross proceeds of $18.5 million, the Company entered into the Third Loan Modification Agreement with its primary lender.  The amendment extended the revolving credit facility maturity to March 31, 2013 and revised the financial covenants.  Additionally, the revolving line of credit was decreased from $20 million to $13 million.  The reduction was as  a result of the pay down of $7 million of the guarantees provided by the Lenders.  In addition the Company and the Lenders agreed to decrease the $10 million guarantee to $3 million and to further extend the loan guarantee through March 31, 2013. The Company granted warrants to purchase an aggregate of 234,305 shares of common stock at $3.361 per share in exchange for the extension of the guarantee.
	On March 29, 2013, the Company amended its agreement with its primary lender. The amendment extended the maturity date of the working capital line of credit from March 31, 2013 to June 30, 2013. The Company and the Lenders also agreed to extend until June 30, 2013 the $3 million guarantee.  As a result of this extension, the Company issued the Lenders warrants to purchase 113,636 shares of common stock at $1.98 per share.
	On June 28, 2013, the Company amended its agreement with its primary lender. The amendment extended the maturity date of the working capital line of credit from June 30, 2013 to July 31, 2013, and decreased the amount of available advances from $13 million to $6 million.  In addition, the Bank waived the testing of the tangible net worth and liquidity ratio financial covenants under the Amended Loan Agreement for the period ended June 30, 2013. The Company and the Lenders also agreed to extend until July 31, 2013 the $3 million guarantee.  As a result of this extension, the Company issued the Lenders warrants to purchase 48,387 shares of common stock at $1.55 per share.
	On July 31, 2013, the Company amended its agreement with its primary lender. The amendment extended the maturity date of the working capital line of credit from July 31, 2013 to August 31, 2013.  In addition, the Bank waived the testing of the liquidity ratio financial covenant under the Amended Loan Agreement for the period ended July 31, 2013. The Company and the Lenders also agreed to extend until August 31, 2013 the $3 million guarantee.  As a result of this extension, the Company issued the Lenders warrants to purchase 14,313 shares of common stock at $5.24 per share.
	On August 30, 2013, the Company amended its agreement with its primary lender. The amendment extended the maturity date of the working capital line of credit from August 31, 2013 to March 31, 2014. In addition, the Company and the Bank agreed to a reduction in the revolving credit line from $6.0 million to $3.0 million, the elimination of the $3.0 million sublimit guaranteed by the Lenders, and release of the guarantees by the Lenders in favor of the Bank. The amendment eliminated the prepayment premium for the prepayment of the term loan and modified the financial covenants to (a) eliminate the minimum tangible net worth covenant, (b) substitute in lieu thereof an EBITDA test, requiring the Company to maintain a minimum EBITDA of no less than (no worse than) (i) negative $4.0 million for the trailing three-month period ending September 30, 2013 and (ii) negative $3.0 million for the trailing three-month period ending December 31, 2013, in each case tested quarterly on a trailing three month basis, and (c) revise the liquidity ratio covenant to require the Company to maintain a liquidity ratio of greater than 2:1, excluding certain short term advances from the calculation.
	As of September 30, 2013, the Company had $3.0 million outstanding under the revolving line of credit.  Draws on the line of credit are made based on the borrowing capacity one week in arrears.  As of September 30, 2013, the Company had a borrowing capacity of $3.0 million based on the Company’s collateralized assets, including amounts already drawn.  As such, the Company had no remaining ability to borrow under the revolving line of credit at September 30, 2013.
	The revolving line of credit and the Company’s term notes (collectively, the “Credit Agreements”) are secured by substantially all of the Company’s assets. The Company is also required under the Credit Agreements to maintain its primary operating account and the majority of its cash and investment balances in accounts with the primary lender.
	Term note
	Under the 2010 amendment to the loan agreement, the Company entered into a $10 million term loan maturing on December 31, 2013, with $2 million of principal due in 2011 and $4 million of principal due in each of 2012 and 2013. Interest on the term loan accrued at the rate of prime plus 3.5%. Under the September 2011 amendment of the loan agreement, the interest rate on the term loan was increased to prime plus 5.5%.  Under this agreement, the Company provided its primary lender with warrants to purchase 11,111 shares of common stock. The warrants are exercisable at $36.00 per share, beginning on December 17, 2010 and expiring on December 17, 2015. The fair value of these warrants of $228,332, calculated using the Black-Scholes method, was deferred and amortized to interest expense ratably over the life of the term loan. The term note was paid in full in September 2013.
	Healthcare Royalty Partners Debt
	In November 2011, the Company entered into a loan agreement with Healthcare Royalty Partners. Under the agreement the Company borrowed from Healthcare Royalty Partners $15 million. The Company was permitted to borrow up to an additional $5 million in the aggregate based on the achievement by the Company of certain milestones related to Niobe system sales in 2012. On August 8, 2012, the Company borrowed an additional $2.5 million based upon achievement of a milestone related to Niobe system sales for the nine months ended June 30, 2012. On January 31, 2013, the Company borrowed an additional $2.5 million based upon achievement of a milestone related to Niobe system sales for the twelve months ended December 31, 2012.  The loan will be repaid through, and secured by, royalties payable to the Company under its Development, Alliance and Supply Agreement with Biosense Webster, Inc. The Biosense Agreement relates to the development and distribution of magnetically enabled catheters used with Stereotaxis' Niobe system in cardiac ablation procedures. Under the terms of the Agreement, Healthcare Royalty Partners will be entitled to receive 100% of all royalties due to the Company under the Biosense Agreement until the loan is repaid.  The loan is a full recourse loan, matures on December 31, 2018, and bears interest at an annual rate of 16% payable quarterly with royalties received under the Biosense Agreement. If the payments received by the Company under the Biosense Agreement are insufficient to pay all amounts of interest due on the loan, then such deficiency will increase the outstanding principal amount on the loan. After the loan obligation is repaid, the royalties under the Biosense Agreement will again be paid to the Company. The loan is also secured by certain assets and intellectual property of the Company. The Agreement also contains customary affirmative and negative covenants. The use of payments due to the Company under the Biosense Agreement was approved by our primary lender under the Amended Loan Agreement described above.
	Subordinated Convertible Debentures
	In May 2012, the Company entered into a securities purchase agreement with certain institutional investors whereby the Company agreed to sell an aggregate of approximately $8.5 million in aggregate principal amount of unsecured, subordinated, convertible debentures (the “Debentures”), which became convertible into shares of the Company’s common stock at a conversion price of $3.361 per share (or approximately 2.5 million shares in the aggregate), on July 10, 2012, the date that the Company received shareholder approval for the transaction.  The purchasers of the Debentures also received six-year warrants to purchase an aggregate of approximately 2.5 million shares of the Company’s common stock at an exercise price of $3.361 per share (“Convert Warrants”).  The Debentures bear interest at 8% per year and mature on May 7, 2014.  In addition, the Company has the ability to issue shares of its common stock in lieu of cash interest payments under certain circumstances, and following the registration of the shares for resale, the Company issued shares in lieu of cash interest payments.
	The Company recorded the Debentures on the balance sheet net of the debt discount.  The debt discount of $7.6 million is due to warrants issued in conjunction with the Debentures and the debt conversion features.  Upon issuance of the Debentures, the fair value of the warrants and derivative liability were $4.1 million and $3.5 million, respectively.  The debt discount was amortized over the life of the loan using the effective interest method and the warrants and derivative liability were recorded at fair value on each reporting period.  Refer to Note 11 for additional discussion of the fair value of the warrants and conversion features.
	On August 7, 2013, holders of Convert Warrants exercised all of their Convert Warrants for an aggregate of approximately 2.5 million shares of our common stock, resulting in cash proceeds of approximately $8.5 million. In addition, holders of all of the Debentures exchanged the balance of their unconverted Debentures for an aggregate of approximately 2.7 million shares of the Company’s common stock and additional warrants (the “Exchange Warrants”) to purchase approximately 2.5 million shares, having an exercise price of $3.361 per share. On August 8, 2013, certain former holders of the Debentures exercised Exchange Warrants to purchase an aggregate of 1,372,358 shares of common stock in cashless net exercises as provided for in the Exchange Warrants, which resulted in the issuance to such funds of an aggregate of 841,575 shares of common stock. As a result, there were no net proceeds to the Company. The Company is relying on the exemption from registration afforded by Section 4(a)(2) of the Securities Act of 1933, as amended, based on representations to the Company made by the warrant holders.
	The costs associated with the adjustment of warrants and convertible debt features in connection with the third quarter capital transactions are included in other expense for the three and nine months ended September 30, 2013.  The costs associated with the write-off of the unamortized debt discount are included in interest expense for the three and nine months ended September 30, 2013.

	Listing Transfer to NASDAQ Capital Market
	On August 15, 2013, the NASDAQ Listing Qualifications Panel (the “Panel”) granted approval of the Company’s request to transfer its listing to The NASDAQ Capital Market® from The NASDAQ Global Market®. The Company’s securities began trading on the NASDAQ Capital Market effective August 19, 2013.
	Reverse Stock Split
	On July 10, 2012, the Company filed a Certificate of Amendment to our Amended and Restated Certificate of Incorporation to implement a one-for-ten reverse split of our common stock (the “Reverse Stock Split”). The ratio for the Reverse Stock Split was determined by our Board of Directors pursuant to the approval of the stockholders at the Company’s special meeting of stockholders held on July 10, 2012, authorizing the Board to effect a reverse stock split within a range of one-for-four to one-for-ten shares of the Company’s common stock. The Reverse Stock Split was effective as of July 10, 2012, and the Company’s common stock began trading on the NASDAQ Global Market on a post-split basis on July 11, 2012.
	As a result of the Reverse Stock Split, each ten shares of the Company’s issued and outstanding common stock were automatically combined and converted into one issued and outstanding share of common stock. The Reverse Stock Split affected all issued and outstanding shares of the Company’s common stock, as well as common stock underlying stock options, stock appreciation rights, restricted stock, restricted stock units, warrants and convertible debentures outstanding immediately prior to the effectiveness of the Reverse Stock Split. The Reverse Stock Split reduced the number of shares of the Company’s common stock outstanding from approximately 78 million to 7.8 million at the time of the Reverse Stock Split. In addition, the Amendment increased the number of authorized shares of the Company’s common stock from 100 million to 300 million. The Reverse Stock Split did not alter the par value of common stock, which remained $0.001 per share, or modify any voting rights or other terms of the Company’s common stock. Unless otherwise indicated, all information set forth herein gives effect to such Reverse Stock Split.
	Private Offerings of Common Stock
	In May 2012, the Company entered into a Stock and Warrant Purchase Agreement with certain institutional investors whereby it agreed to sell an aggregate of approximately 2.17 million shares of the Company's common stock (the “PIPE Common Stock”) at a price of $3.361 per share, together with six-year warrants at a price of $1.25 per share to purchase an aggregate of approximately 2.17 million shares of common stock having an exercise price of $3.361 per share (the “PIPE Warrants”). Each purchaser received a PIPE Warrant to purchase one share of common stock for every share of PIPE Common Stock purchased.
	Net proceeds from the sale of the securities were approximately $9.1 million, after placement agent fees and other offering expenses.  The Company used the funds to repay $7 million of the revolving credit facility guaranteed by the Lenders and plans to use the balance for working capital and general corporate purposes.
	On August 7, 2013, venture funds affiliated with Sanderling Ventures received an aggregate of 183,478 shares of common stock based upon the cashless exercise of warrants to purchase an aggregate of 262,450 shares of common stock. These warrants were comprised of 75,758 warrants with an exercise price of $1.98 per share, 156,204 warrants with an exercise price of $3.361 per share and 30,488 warrants with an exercise price of $4.10 per share. The warrants were issued by the Company in private placements in 2012 and 2013 in connection with the extension of previously disclosed guarantees.
	On August 13, 2013, venture funds affiliated with Sanderling Ventures exercised PIPE Warrants to purchase an aggregate of 650,619 shares of common stock in a cashless net exercise as provided for in the PIPE Warrants, which resulted in the issuance to such funds of an aggregate of 308,194 shares of common stock. As a result, there were no net proceeds to the Company.
	On August 16, 2013, certain affiliates of Franklin Templeton exercised PIPE Warrants to purchase an aggregate of 650,618 shares of common stock for cash. The Company received an aggregate of $2,186,727 gross proceeds from the sale.
	On August 16, 2013, Alafi Capital Company exercised PIPE Warrants to purchase an aggregate of 261,241 shares of common stock for cash. The Company received an aggregate of $878,031 gross proceeds from the sale.
	Stock Award Plans
	The Company has various stock plans that permit the Company to provide incentives to employees and directors of the Company in the form of equity compensation.  In August 2012, the Board of Directors adopted a stock incentive plan (the 2012 Stock Incentive Plan) which was subsequently approved by the Company’s stockholders. This plan replaces the 2002 Stock Incentive Plan which expired on March 25, 2012.  At September 30, 2013, the Board of Directors had 1,033,242  remaining shares of the Company’s common stock to provide for current and future grants under its various equity plans.
	At September 30, 2013, the total compensation cost related to options, stock appreciation rights and non-vested stock granted to employees under the Company’s stock award plans but not yet recognized was approximately $1.7 million, net of estimated forfeitures of approximately $1.6 million. This cost will be amortized over a period of up to four years over the underlying estimated service periods and will be adjusted for subsequent changes in estimated forfeitures and anticipated vesting periods.

Fair Value Measurements	'
	11. Fair Value Measurements
	The Company measures certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents and warrants. General accounting principles for fair value measurement established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (“Level 1”) and the lowest priority to unobservable inputs (“Level 3”). The three levels of the fair value hierarchy are described below:
	Level 1: Values are based on unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
	Level 2: Values are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, or other model-based valuation techniques for which all significant assumptions are observable in the market.
	Level 3: Values are generated from model-based techniques that use significant assumptions not observable in the market.
	The following table sets forth the Company’s assets and liabilities measured at fair value on a recurring basis by level within the fair value hierarchy.  As required by the Fair Value Measurements and Disclosures topic of the Accounting Standards Codification, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

	Level 1
	The Company’s financial assets consist of cash equivalents invested in money market funds in the amount of $4,550,340 and $256,702 at September 30, 2013 and December 31, 2012, respectively. These assets are classified as Level 1 as described above and total interest income recorded for these investments was insignificant during both the nine month periods ended September 30, 2013 and September 30, 2012. There were no transfers in or out of Level 1 during the period ended September 30, 2013.
	Level 2
	The Company does not have any financial assets or liabilities classified as Level 2.
	Level 3
	In conjunction with its December 29, 2008 registered direct offering, the Company issued warrants to purchase 179,241 shares of the Company’s common stock that contained a provision that required a reduction of the exercise price if certain equity events occurred. Under the provisions of general accounting principles for derivatives and hedging activities and determining whether an instrument (or embedded feature) is indexed to an entity’s own stock, such a reset provision does not meet the exemptions for equity classification and as such, the Company accounts for these warrants as derivative instruments. The calculated fair value of the warrants is classified as a liability and is periodically remeasured with any changes in value recognized in “Other income (expense)” in the Statement of Operations. General accounting principles for determining whether an instrument (or embedded feature) is indexed to an entity’s own stock became effective for the Company as of January 1, 2009. Accordingly, the fair value of the warrants as of that date was reclassified from stockholders’ equity into current liabilities.
	In accordance with general accounting principles for fair value measurement, the Company’s warrants in the amount of $256,650 were measured at fair value on a recurring basis as of September 30, 2013 and were valued using Level 3 valuation inputs. A Black-Scholes model was used to value the Company’s warrants at September 30, 2013 using the following assumptions: 1) dividend yield of 0%; 2) volatility of 232.47%; 3) risk-free interest rate of 0.63%; and 4) expected life of 0.74 of a year.
	In the Company’s May 2012 financing transaction, the Company issued subordinated convertible debentures and warrants.  The optional conversion feature of the subordinated convertible debentures is classified as a derivative liability within “Warrants and debt conversion features” on the Company’s balance sheet.  In August 2013, holders of all of the Debentures exchanged the balance of their unconverted Debentures for an aggregate of approximately 2.7 million shares of the Company’s common stock and additional warrants (the “Exchange Warrants”) to purchase approximately 2.5 million shares, having an exercise price of $3.361 per share.  The warrants issued in conjunction with the May 2012 Debentures and PIPE and the August 2013 Exchange are also considered a liability.  Due to the provisions included in the warrant agreements, the warrants do not meet the exemptions for equity classification and as such, the Company accounts for these warrants as derivative instruments. The warrants and derivative liability are periodically remeasured with any changes in value recognized in “Other income (expense)” in the Statement of Operations.
	Per the terms of the Debentures agreement, the Company had the ability to require each holder to convert up to 50% of the Debentures if the common stock closed above $15.00, or 100% of the Debentures if the common stock closed above $20.00 (in each case, as adjusted for stock splits, recapitalizations and similar events) during a 20 consecutive trading day period and the resale registration statement had been declared effective by the SEC and was available for the issuance of the common stock upon conversion of the Debentures. In the event of any forced conversion by the Company, the minimum amount that the Company could force the holders to convert was  $2.5 million of Debentures in the aggregate.  This mandatory redemption clause was classified as a derivative asset within “Prepaid and other current assets” on the Company’s balance sheet. The derivative asset was periodically remeasured with any changes in value recognized in “Other income (expense)” in the Statement of Operations.
	Based on the discussion of the Debentures in Note 9, the Debentures along with their derivative liability and asset, and related warrants were extinguished prior to September 30, 2013. In accordance with general accounting principles for fair value measurement, the Company’s remaining PIPE and Exchange warrants were measured at fair value on a recurring basis as of September 30, 2013 and were valued using Level 3 valuation inputs.  A Monte-Carlo simulation was used to value the derivative asset, liabilities and warrants upon issuance on May 10, 2012 using the following assumptions: 1) volatility of 80%; 2) risk-free interest rate of 1.035%; and 3) a closing stock price of $3.413.
	The initial valuation of Exchange warrants were valued as of August 7, 2013 using the following assumptions: 1) volatility of 111%; 2) risk-free interest rate of 1.46%; and 3) a closing stock price of $8.69.
	The remaining Exchange warrants were revalued as of September 30, 2013 using the following assumptions: 1) volatility of 115%; 2) risk-free interest rate of 1.43%; and 3) a closing stock price of $3.33.
	The remaining PIPE warrants were revalued as of September 30, 2013 using the following assumptions: 1) volatility of 115%; 2) risk-free interest rate of 1.24%; and 3) a closing stock price of $3.33.
	The significant unobservable input used in the fair value measurement of the Company’s warrants, derivative liability, and derivative asset is volatility.  Significant increases (decreases) in the volatility in isolation would result in a significantly higher (lower) asset and liability fair value measurements.
	The following table sets forth a summary of changes in the fair value of the Company’s Level 3 financial asset and liabilities for the nine month period ended September 30, 2013:
		Derivative Asset		Total Assets		Warrants issued December 29, 2008		Warrants issued May 2012		Warrants issued August 2013	Derivative Liability	Total Liabilities

	The Company currently does not have derivative instruments to manage its exposure to currency fluctuations or other business risks. The Company evaluates all of its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives. All derivative financial instruments are recognized in the balance sheet at fair value.

	On October 29, 2013, we filed a prospectus with the Securities Exchange Commission relating to a rights offering in which all stockholders and certain warrant holders of Stereotaxis, Inc. received subscription rights to purchase an aggregate of up to 6,315,953 shares of our common stock, par value $0.001 per share.  All stockholders and certain warrant holders received subscription rights to purchase 1 share of common stock at a price of $3.00 per share for every 3 shares of stock that they held as of the record date of October 31, 2013.  The NASDAQ Capital Market established Monday, November 4, 2013 as the “ex-rights” date for the rights offering. The ex-rights date is the date on which Stereotaxis’s common stock began to trade without the rights and the rights began to trade separately from the common stock. Between the record date and the ex-rights date, the rights traded together with the shares of common stock. The rights are listed on the NASDAQ Capital Market under the symbol “STXSR,” and will continue to be so listed until the expiration of the rights offering. The subscription rights will be exercisable until November 21, 2013 unless we choose to extend the rights offering beyond this date, which we do not currently expect to do.

Summary Of Significant Accounting Policies [Abstract]	'
Basis Of Presentation	'
	Basis of Presentation
	The accompanying unaudited financial statements of Stereotaxis, Inc. have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all the disclosures required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, they include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods presented. Operating results for the nine month period ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ended December 31, 2013 or for future operating periods.
	These interim financial statements and the related notes should be read in conjunction with the annual financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012 as filed with the Securities and Exchange Commission (SEC) on April 1, 2013.
	As described in Note 10, on July 10, 2012, the Company effected a one-for-ten reverse stock split of the Company’s common stock. All information set forth in the financial statements and related notes gives effect to such reverse stock split.
Financial Instruments	'
	Financial Instruments
	The Company measures certain financial assets and liabilities at fair value on a recurring basis, including warrants and debt conversion features. General accounting principles for fair value measurement established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (“Level 1”) and the lowest priority to unobservable inputs (“Level 3”). See Note 11 for additional details.
	The following methods and assumptions were used by the Company in estimating its fair value disclosures for other financial instruments as of September 30, 2013 and December 31, 2012.
	Cash equivalents, accounts receivable, and accounts payable have carrying values which approximate fair value due to the short maturity or the financial nature of these instruments.
	Long and short-term debt fair value estimates are based on estimated borrowing rates to discount the cash flows to their present value. See Note 9 for disclosure of the fair value of debt.
Revenue And Costs Of Revenue	'
	Revenue and Costs of Revenue
	For arrangements with multiple deliverables, the Company allocates the total revenue to each deliverable based on the provisions of general accounting principles for revenue recognition and multiple-deliverable revenue arrangements and recognizes revenue for each separate element as the criteria for revenue recognition are met. Each element is assigned an estimated selling price using vendor-specific objective evidence, third party evidence, or management’s estimate.
	Under our revenue recognition policy, a portion of revenue for the Niobe,  Odyssey Vision, Odyssey Cinema, and Vdrive systems is recognized upon delivery, provided that title has passed, there are no uncertainties regarding acceptance, persuasive evidence of an arrangement exists, the sales price is fixed and determinable, and collection of the related receivable is reasonably assured. Revenue for Niobe, Odyssey Vision Standard HD, Odyssey Vision Quad, Odyssey Cinema, and Vdrive systems is recognized upon delivery due to the fact that third parties became qualified to perform installations. Revenue is recognized for other types of Odyssey systems upon completion of installation, since there are no qualified third party installers. When installation is the responsibility of the customer, revenue from system sales is recognized upon shipment since these arrangements do not include an installation element or right of return privileges. The Company does not recognize revenue in situations in which inventory remains at a Stereotaxis warehouse or in situations in which title and risk of loss have not transferred to the customer. However, the Company may deliver systems to a non-hospital site at the customer’s request as outlined in the terms and conditions of the sales agreement, in which case the Company evaluates whether the substance of the transaction meets the delivery and performance requirements for revenue recognition under “bill and hold” guidance. Amounts collected prior to satisfying the above revenue recognition criteria are reflected as deferred revenue.
	Revenue from services and license fees, whether sold individually or as a separate unit of accounting in a multiple-deliverable arrangement, is deferred and amortized over the service or license fee period, which is typically one year. Revenue from services is derived primarily from the sale of annual product maintenance plans. We recognize revenue from disposable device sales or accessories upon shipment and establish an appropriate reserve for returns. The return reserve, which is applicable only to disposable devices, is estimated based on historical experience which is periodically reviewed and updated as necessary. In the past, changes in estimate have had only a de minimus effect on revenue recognized in the period. We believe that the estimate is not likely to change significantly in the future.
	Costs of systems revenue include direct product costs, installation labor and other costs, estimated warranty costs, and initial training and product maintenance costs. These costs are recorded at the time of sale. Costs of disposable revenue include direct product costs and estimated warranty costs and are recorded at the time of sale. Cost of revenue from services and license fees are recorded when incurred.
Share-Based Compensation	'
	Share-Based Compensation
	The Company accounts for its grants of stock options, stock appreciation rights, restricted shares, and restricted stock units and for its employee stock purchase plan in accordance with the provisions of general accounting principles for share-based payments. These accounting principles require the determination of the fair value of the share-based compensation at the grant date and the recognition of the related expense over the period in which the share-based compensation vests.
	The Company utilizes the Black-Scholes valuation model to determine the fair value of stock options and stock appreciation rights at the date of grant. The resulting compensation expense is recognized over the requisite service period, which is generally four years. Compensation expense is recognized only for those awards expected to vest, with forfeitures estimated based on the Company’s historical experience and future expectations. Restricted shares granted to employees are valued at the fair market value at the date of grant. The Company amortizes the fair market value to expense over the service period. If the shares are subject to performance objectives, the resulting compensation expense is amortized over the anticipated vesting period and is subject to adjustment based on the actual achievement of objectives.
Net Loss Per Common Share	'
	Net Loss per Common Share (“EPS”)
	Basic and diluted net loss per common share (“EPS”) is computed by dividing the net loss for the period by the weighted average number of common shares outstanding during the period.
	The following table sets forth the computation of basic and diluted EPS:
		Three months ended September 30,				Nine months ended September 30,
		2013		2012		2013		2012
	Numerator:
	Numerator for basic EPS	$	-56,868,442	$	-1,915,281	$	-64,795,382	$	-4,921,766

	Numerator for diluted EPS	$	-56,868,442	$	-1,915,281	$	-64,795,382	$	-4,921,766
	Denominator:
	Denominator for basic EPS—weighted average shares		12,666,414		7,701,332		9,640,249		6,651,255
	Effect of dilutive securities:
	Subordinated convertible debentures		—		—		—		—
	Denominator for diluted EPS		12,666,414		7,701,332		9,640,249		6,651,255
	Basic EPS	$	-4.49	$	-0.25	$	-6.72	$	-0.74
	Diluted EPS	$	-4.49	$	-0.25	$	-6.72	$	-0.74
	In addition, the Company did not include any portion of unearned restricted shares, outstanding options, stock appreciation rights or warrants in the calculation of diluted loss per common share because all such securities are anti-dilutive for the three and nine months ended September 30, 2013 and the three and nine months ended September 30, 2012. The application of the two-class method of computing earnings per share under general accounting principles for participating securities is not applicable during these periods because the Company’s unearned restricted shares do not contractually participate in its losses.
	As of September  30, 2013, the Company had 238,989 shares of common stock issuable upon the exercise of outstanding options and stock appreciation rights at a weighted average exercise price of $46.83 per share and 3,021,302 shares of common stock issuable upon the exercise of outstanding warrants at a weighted average exercise price of $14.30 per share. The Company had a weighted average of 25,657 and 36,135 unearned restricted shares outstanding for the three and nine months period ended September 30, 2013.
