Organization Consolidation And Presentation Of Financial Statements [Abstract]
The Company and its Significant Accounting Policies	Note 1. The Company and its Significant Accounting Policies The Company Accuray Incorporated (together with its subsidiaries, the “Company” or “Accuray”) designs, develops and sells advanced radiosurgery and radiation therapy systems for the treatment of tumors throughout the body. The Company is incorporated in Delaware and has its principal place of business in Sunnyvale, California. The Company has primary offices in the United States, Switzerland, China, Hong Kong and Japan and conducts its business worldwide. Basis of Presentation The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant inter-company transactions and balances have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”), pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and note disclosures have been condensed or omitted pursuant to such rules and regulations. The unaudited condensed consolidated financial statements have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair presentation of the periods presented. The results for the three and nine months ended March 31, 2019 are not necessarily indicative of the results to be expected for the fiscal year ending June 30, 2019, or for any other future interim period or fiscal year. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes for the fiscal year ended June 30, 2018 included in the Company’s Annual Report on Form 10-K filed with the SEC on August 24, 2018. Significant Accounting Policies The Company adopted Accounting Standard Codification (“ASC”) 606, Revenue from Contracts with Customers Recent Accounting Pronouncements Revenue . The Company and its Significant Accounting Policies Revenue Recognition The Company’s revenue is primarily derived from sales of CyberKnife and TomoTherapy Systems and services, which include post-contract customer support (“PCS”), installation services, training and other professional services. The Company has a contract with a customer when there is approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. The Company's revenues are measured based on consideration specified in the contract with each customer, net of any sales incentives and amounts collected on behalf of third parties such as sales taxes, excise taxes, and VAT. The majority of the Company's revenue arrangements consists of multiple performance obligations, which can include system, upgrades, installation, training, services, construction, and consumables. For bundled arrangements, the Company accounts for individual products and services separately if a product or service is separately identifiable from other items in the bundled package and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company’s products are generally not sold with a right of return, and the Company’s contracts generally provide a fixed transaction price. However, the Company from time to time offers variable consideration such as volume discounts. The Company also from time to time offers extended payment terms beyond one year, trade-in allowance for old systems, and commissions or other forms of payment to customers. The Company applied the practical expedient to not adjust for a significant financing component if the gap between payment and delivery was expected, at the contract inception, to be less than one year. The stand-alone selling price (“SSP”) of performance obligations is determined based on observable prices at which the Company separately sells the products and services. If the SSP is not directly observable, then the Company will estimate the SSP considering market conditions, entity-specific factors, and information about the customer or class of customer that is reasonably available. The SSP is generally assessed as a percentage of the list price. The contract consideration allocation is based on the SSP at contract inception. The consideration (net of any discounts) is allocated among separate products and services in a bundle based on their individual SSP. For contract modifications that add additional goods or services or changes pricing, the most recent SSP is used for allocation to the remaining performance obligations. The Company recognizes revenue for certain performance obligations at the point in time when control is transferred, such as delivery of products. The Company recognizes revenue for certain other performance obligations over a period of time as control of the goods or services is transferred, such as PCS and construction contracts. The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if the Company expects the benefit of those costs to be longer than one year. The Company capitalizes incremental contract acquisition costs, and amortizes such costs over the period which the Company expects to benefit, which may extend beyond the initial contract term. Most of the Company’s contract costs are associated with its internal sales force compensation program and a portion of its employee bonus program. The Company amortizes capitalized bonuses and a portion of sales commissions over a period of five years commencing upon the initial transfer of control of the system to the customer. The pattern of amortization is commensurate with the pattern of transfer of control of the performance obligations to the customer. The Company elected to use the practical expedient in ASC 340-40-25-4 and expense as incurred commissions related to service renewals and upgrades because the contract term is less than a year.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606 The Company completed its assessment of the impact this guidance has on its consolidated financial statements and related disclosures. Based on that assessment, the Company concluded the significant impact areas were the capitalization and amortization of incremental costs of obtaining a contract, primarily related to certain bonuses and sales commissions, change in SSP and the removal of software revenue recognition rules along with the elimination of revenue deferral for cash basis customers. Under the new standards, the Company capitalizes incremental contract acquisition costs, such as certain bonuses and sales commissions, and amortizes such costs over the period which the Company benefits, as estimated by management, which may extend beyond the initial contract term. The Company amortizes capitalized bonuses and sales commissions over a period of five years commencing upon the initial transfer of control of the system to the customer. The pattern of amortization is commensurate with the pattern of transfer of control of the performance obligations to the customer. The Company elected to use the practical expedient in ASC 340-40-25-4 and expense commissions related to service renewals and upgrades with a renewal contract term of one year or less as incurred. The Company recorded a net reduction to opening accumulated deficit of $5.1 million, net of tax, as of July 1, 2018 due to the cumulative impact of adopting ASC 606, with the impact primarily related to the deferral of incremental costs to obtain contracts. Under ASC 606, product revenue for direct sales are accelerated to reflect transfer of control upon delivery while an element of installation is deferred until performed. Prior to the adoption of ASC 606, the Company deferred revenue until installation had occurred. The revenue recognition method for indirect sales and service revenues is unchanged under the new guidance.

The beginning net cumulative-effect adjustment to retained earnings for the adoption of ASC 606 is as follows: Balance as Balance at Adjustment Reported at (Dollars in thousands) July 1, 2018 ASC 606 June 30, 2018 Assets: Account receivable, net $ 66,251 $ 257 $ 65,994 Deferred cost of revenue - current 677 (464 ) 1,141 Prepaid expenses and other current assets 16,239 670 15,569 Other assets 17,416 5,840 11,576 Liabilities and Stockholders' Equity: Other accrued liabilities 23,059 611 22,448 Deferred revenue - current 75,515 111 75,404 Long-term other liabilities 9,075 467 8,608 Accumulated deficit (469,171 ) 5,114 (474,285 ) Select unaudited condensed consolidated balance sheets line items, which reflect the adoption of ASC 606 are as follows: March 31, 2019 (Dollars in thousands) As Reported Adjustments Balances Without Adoption Assets: Account receivable, net $ 99,774 $ 5,698 $ 94,076 Deferred cost of revenue - current 157 (7,301 ) 7,458 Prepaid expenses and other current assets 21,452 2,262 19,190 Other assets 16,180 6,666 9,514 Liabilities and Stockholders' Equity: Other accrued liabilities 26,945 760 26,185 Deferred revenue - current 78,833 (8,553 ) 87,386 Long-term other liabilities 8,168 1,857 6,311 Accumulated deficit (484,140 ) 13,261 (497,401 ) Select unaudited condensed consolidated statements of operations and comprehensive loss line items for the three and nine months ended March 31, 2019, which reflect the adoption of ASC 606 are as follows: Three Months Ended March 31, 2019 Nine Months Ended March 31, 2019 (Dollars in thousands) As Reported Adjustments Balances Without Adoption As Reported Adjustments Balances Without Adoption Net revenue $ 103,221 $ (10,491 ) $ 113,712 $ 301,368 $ 13,352 $ 288,016 Cost of goods sold 62,755 (5,101 ) 67,856 184,643 6,605 178,038 Other expense, net 3,829 (190 ) 4,019 11,133 (449 ) 11,582 Research and development 12,913 (43 ) 12,956 40,442 (179 ) 40,621 Selling and marketing 12,903 (98 ) 13,001 41,078 (557 ) 41,635 General and administrative 11,769 (94 ) 11,863 37,880 (383 ) 38,263 Provision for income taxes 236 198 38 1,222 168 1,054 Net loss (1,184 ) (5,163 ) 3,979 (15,030 ) 8,147 (23,177 ) Net loss per share - basic and diluted $ (0.01 ) $ (0.06 ) $ 0.05 $ (0.17 ) $ 0.09 $ (0.27 ) The adoption of ASC 606 had no impact to net cash from or used in operating, investing or financing activities in the Company's unaudited condensed consolidated statements of cash flows. Contract Balances The timing of revenue recognition, billings, and cash collections results in trade, unbilled receivables, and deferred revenues on the unaudited condensed consolidated statement of balance sheets. The Company may offer longer or extended payments of more than one year for qualified customers in some circumstances. At times, revenue recognition occurs before the billing, resulting in an unbilled receivable, which represents a contract asset. The contract asset is a component of accounts receivable and other assets for the current and non-current portions, respectively. When the Company receives advances or deposits from customers before revenue is recognized, this results in a contract liability. It can take up to two and half years from the time of order to revenue recognition due to the Company’s long sales cycle. Changes in the contract assets and contract liabilities are as follows: March 31, 2019 July 2018 Change (Dollars in thousands) Amount Amount $ % Assets: Unbilled accounts receivable – current (1) $ 8,016 $ 3,218 4,798 60 Interest receivable – current (2) 239 — 239 100 Long-term accounts receivable (3) 3,949 6,833 (2,884 ) (73 ) Interest receivable – non-current (3) 1,232 611 621 50 Liabilities: Customer advances 22,822 22,896 (74 ) — Deferred revenue – current 78,833 75,515 3,318 4 Deferred revenue – non-current 23,291 20,976 2,315 10 (1) Included in accounts receivable on consolidated balance sheets (2) Included in prepaid expenses and other current assets on consolidated balance sheets ( 3 ) Included in other assets on consolidated balance sheets Changes in deferred revenue from contracts with customers are as follows: Three Months Ended Nine Months Ended (Dollars in thousands) March 31, 2019 March 31, 2019 Balance at beginning of period $ 96,132 $ 96,491 New billings 109,213 307,001 Recognition of deferred revenue (103,221 ) (301,368 ) Balance at end of period $ 102,124 $ 102,124 During the three months ended March 31, 2019, the Company recognized revenues of $14.7 million, which were included in the deferred revenues balance at December 31, 2018. During the nine months ended March 31, 2019, the Company recognized revenues of $57.8 million, which were included in the deferred revenues balance at June 31, 2018. Remaining Performance Obligations Remaining performance obligations represent deferred revenue from open contracts for which performance has already started and the transaction price from signed contracts for which performance has not yet started. Service contracts in general are considered month-to-month contracts, and the Company has elected the practical expedient available in the guidance related to ASC 606, to not disclose the value of unsatisfied performance obligations for contracts with an original expected duration of one year or less. As of March 31, 2019, total remaining performance obligations amounted to $830.1 million. Of this total amount, $72.0 million related to long-term warranty and service, which is expected to be recognized over the remaining warranty period for systems that have been delivered. For systems that have been delivered but not yet installed, management estimates the timing of installation since warranty starts upon installation. The following table represents the Company's remaining performance obligations related to long-term warranty and service as of March 31, 2019 and the estimated revenue expected to be recognized: Fiscal years of revenue recognition (Dollars in thousands) 2019 2020 2021 Thereafter Long-term warranty and service $ 8,597 $ 29,187 $ 21,144 $ 13,113 For the remaining $758.1 million of performance obligations, the Company estimates 25% to 35% will be recognized in the next 12 months, and the remaining 65% to 75% will be recognized in the 30 months thereafter. The Company’s historical experience indicates that some of its customers will cancel or renegotiate contracts as economic conditions change or when product offerings change during the long sales cycle. As such, about 15% to 25% of the Company’s contracts may never result in revenue due to cancellation. The time bands reflect management’s best estimate of when the Company will transfer control to the customer and may change based on timing of shipment, readiness of customers’ facilities for installation, installation requirements, and availability of products. Capitalized Contract Costs The Company capitalizes and amortizes the incremental costs of obtaining a contract, primarily related to certain bonuses and sales commissions. The capitalized bonuses and sales commissions are amortized over a period of five years commencing upon the initial transfer of control of the system to the customer. The pattern of amortization is commensurate with the pattern of transfer of control of the performance obligations to the customer. The opening balance of capitalized costs to obtain a contract was $5.9 million as of July 1, 2018. As of March 31, 2019, the balance of capitalized costs to obtain a contract was $7.3 million. The Company has classified the capitalized costs to obtain a contract as a component of prepaid expenses and other current assets and other assets with respect to the current and non-current portions of capitalized costs, respectively, on the consolidated balance sheets. The Company incurred a de minimis impairment loss for the periods presented. During the three and nine months ended March 31, 2019, the Company recognized $0.5 million and $1.8 million, respectively, in expense related to the amortization of the capitalized contract costs.

Supplemental Financial Information	Note 4. Supplemental Financial Information Balance Sheet Components Financing receivables A financing receivable is a contractual right to receive money, on demand or on fixed or determinable dates, that is recognized as an asset on the Company’s balance sheet. The Company’s financing receivables, consisting of its accounts receivable with contractual maturities of more than one year and sales-type leases, totaled $3.8 million and $6.9 million at March 31, 2019 and June 30, 2018, respectively, and are included in other assets in the unaudited condensed consolidated balance sheets. The Company evaluates the credit quality of an obligor at lease or contract inception and monitors credit quality over the term of the underlying transactions. The Company performs a credit analysis for all new customers and reviews payment history, current order backlog, financial performance of the customers and other variables that augment or mitigate the inherent credit risk of a transaction. Such variables include the underlying value and liquidity of the collateral, the essential use of the equipment, the term of the lease and the inclusion of credit enhancements, such as guarantees, letters of credit or security deposits. The Company classifies accounts as high risk when it considers the financing receivable to be impaired or when management believes there is a significant near-term risk of non-payment. The Company performed an assessment of the allowance for credit losses related to its financing receivables as of March 31, 2019 and June 30, 2018. Based upon such assessment, the Company recorded a $3.3 million and zero adjustment to the allowance for credit losses related to such financing receivables as of March 31, 2019 and as of June 30, 2018, respectively. A summary of the Company’s financing receivables is presented as follows (in thousands): March 31, 2019 Lease Receivables Financed Service Contracts and Other Total Gross $ — $ 12,677 $ 12,677 Unearned income — (1,474 ) (1,474 ) Allowance for credit loss — (3,327 ) (3,327 ) Total, net $ — $ 7,876 $ 7,876 Reported as: Current $ — $ 4,068 4,068 Non-current — 3,808 3,808 Total, net $ — $ 7,876 $ 7,876 June 30, 2018 Lease Receivables Financed Service Contracts and Other Total Gross $ 1,588 $ 8,009 $ 9,597 Unearned income (137 ) — $ (137 ) Allowance for credit loss — — $ — Total, net $ 1,451 $ 8,009 $ 9,460 Reported as: Current $ 432 $ 2,139 $ 2,571 Non-current 1,019 5,870 6,889 Total, net $ 1,451 $ 8,009 $ 9,460 Actual cash collections may differ from the contracted maturities due to early customer buyouts, refinancing, or defaults. In December 2018, one customer bought out the last system that was on lease. As a result, there was no lease receivables as of March 31, 2019.

Depreciation expense related to property and equipment for the three and nine months ended March 31, 2018 was $2.3 million and $7.3 million, respectively. Accumulated Other Comprehensive Income The changes in accumulated other comprehensive income are excluded from earnings and reported as a component of stockholders’ equity. The foreign currency translation adjustment results from those subsidiaries not using the U.S. Dollar as their functional currency since the majority of their economic activities are primarily denominated in their applicable local currency. Accordingly, all assets and liabilities related to these operations are translated to the U.S. Dollar at the current exchange rates at the end of each period. Revenues and expenses are translated at average exchange rates in effect during the period. The components of accumulated other comprehensive income in the equity section of the balance sheets are as follows (in thousands): March 31, 2019 June 30, 2018 Cumulative foreign currency translation adjustment $ 633 $ 1,237 Defined benefit pension obligation (144 ) (144 ) Accumulated other comprehensive income $ 489 $ 1,093

Investments	Note 6. Investments The Company considers all highly liquid investments held at major banks, certificates of deposit and other securities with original maturities of three months or less to be cash equivalents. The Company classifies all of its investments as available-for-sale at the time of purchase because management intends that these investments are available for current operations and includes these investments on its balance sheet as short-term investments. Investments with original maturities longer than three months include commercial paper, U.S. agency securities, non-U.S. government securities and investment-grade corporate debt securities. Investments classified as available-for-sale are recorded at fair market value with the related unrealized gains and losses included in accumulated other comprehensive income, a component of stockholders’ equity. Realized gains and losses are recorded based on specific identification of each security’s cost basis. The Company sold all of its investments in fiscal 2018 and as such, no investments were outstanding as of March 31, 2019 and June 30, 2018.

Derivative Financial Instruments	Note 7. Derivative Financial Instruments The Company manages some of its foreign currency risk through the purchase of foreign currency forward contracts that hedge against the short-term effect of currency fluctuations. These foreign currency forward contracts have a monthly maturity that mitigates the effect of rate fluctuations on certain local currency denominated intercompany balances, cash, and customer receivables. The Company does not use derivative financial instruments for speculative or trading purposes. These forward contracts are not designated as hedging instruments for accounting purposes. Principal hedged currencies include the Euro, Japanese Yen, Swiss Franc, and U.S. Dollar. There were no outstanding foreign currency forward contracts at the end of March 31, 2019 and June 30, 2018.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 8. Fair Value Measurements Fair value is an exit price representing the amount that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The fair value hierarchy contains three levels of inputs that may be used to measure fair value, as follows: Level 1— Unadjusted quoted prices that are available in active markets for the identical assets or liabilities at the measurement date. Level 2— Other observable inputs available at the measurement date, other than quoted prices included in Level 1, either directly or indirectly, including: • Quoted prices for similar assets or liabilities in active markets; • Quoted prices for identical or similar assets in non-active markets; • Inputs other than quoted prices that are observable for the asset or liability; and • Inputs that are derived principally from or corroborated by other observable market data. Level 3— Unobservable inputs that cannot be corroborated by observable market data and require the use of significant management judgment. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. The Company does not carry any investments, and its cash balance was $62.5 million and $83.1 million at March 31, 2019 and June 30, 2018, respectively. Liabilities That Are Measured at Fair Value on a Nonrecurring Basis The Company’s convertible debt is measured on a non-recurring basis using Level 2 inputs based upon observable inputs of the Company’s underlying stock price and the time value of the conversion option since an observable quoted price of the 3.75% Convertible Notes (as defined below) is not readily available. The Revolving Credit Facility (as defined below) and the Term Loan (as defined below) (collectively the “Credit Facilities”) are valued at market interest rates, which it considers to be a level 2 fair value measurement. The carrying value of these financial instruments approximate its estimated fair value as there have not been significant changes in the Company’s credit quality or capital markets that would suggest changes in interest rates since the Credit Facilities were issued or amended in December 2018. The following table summarizes the carrying value and estimated fair value of the Credit Facilities and the 3.75% Convertible Notes (in thousands): March 31, 2019 June 30, 2018 Carrying Value Fair Value Carrying Value Fair Value 3.75% Convertible Notes $ 71,871 $ 92,786 $ 69,382 $ 70,742 Term Loan Facility 43,589 43,589 38,010 38,010 Revolving Credit Facility 30,497 30,497 23,685 23,685 Total $ 145,957 $ 166,872 $ 131,077 $ 132,437

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 9. Commitments and Contingencies Litigation From time to time, the Company is involved in legal proceedings arising in the ordinary course of its business. The Company records a provision for a loss when it believes that it is both probable that a loss has been incurred and the amount can be reasonably estimated. Currently, management believes the Company does not have any probable and estimable losses related to legal proceedings and claims. Although occasional adverse decisions or settlements may occur, management does not believe that an adverse determination with respect to any of these claims would individually or in the aggregate materially and adversely affect the Company’s financial condition or operating results. Litigation is inherently unpredictable and is subject to significant uncertainties, some of which are beyond the Company’s control. Should any of these estimates and assumptions change or prove to have been incorrect, the Company could incur significant charges related to legal matters that could have a material impact on its results of operations, financial position and cash flows. Software License Indemnity Under the terms of the Company’s software license agreements with its customers, the Company agrees that in the event the software sold infringes upon any patent, copyright, trademark, or any other proprietary right of a third-party, it will indemnify its customer licensees against any loss, expense, or liability from any damages that may be awarded against them. The Company includes this infringement indemnification in all of its software license agreements and selected managed services arrangements. In the event the customer cannot use the software or service due to infringement and the Company cannot obtain the right to use, replace or modify the license or service in a commercially feasible manner so that it no longer infringes, then the Company may terminate the license and provide the customer a refund of the fees paid by the customer for the infringing license or service. The Company has not recorded any liability associated with this indemnification, as it is not aware of any pending or threatened actions that represent probable losses as of March 31, 2019. Facility Lease Termination In the third quarter of fiscal 2019, the Company amended a facility lease agreement with the landlord, which reduced the leased space by approximately 39,678 square feet, effective February 28, 2019. Upon termination, the Company removed the deferred rent balance associated with the previously leased space and recorded a $1.0 million credit in the statement of operations.

Debt Disclosure [Abstract]
Debt	Note 10. Debt 3.50% Convertible Senior Notes due February 2018 In February 2013, the Company issued 3.50% Convertible Senior Notes due 2018 (the “3.50% Convertible Notes”) under an indenture between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee. Holders of the 3.50% Convertible Notes were entitled to convert their notes at any time until the close of the business day immediately preceding the maturity date of February 1, 2018. The 3.50% Convertible Notes were convertible into common stock of the Company at an initial conversion rate equal to 187.6877 shares of common stock per $1,000 principal amount, which was equivalent to a conversion price of approximately $5.33 per share of common stock, subject to adjustment. On January 30, 2018, the Company entered into exchange agreements (the “Exchange Agreements”) with the holders of the 3.50% Convertible Notes, which amended the original settlement terms of the notes and allowed the Company to settle the then outstanding $13.0 million principal balance of the 3.50% Convertible Notes and accrued interest in cash at maturity, and any excess equity value over the original conversion price in shares. In exchange for the agreement to settle in cash, the Company agreed to pay a $0.3 million exchange premium. The $0.3 million exchange premium was accounted for as debt extinguishment and included in other expense, net. On February 1, 2018, pursuant to the Exchange Agreements, the Company paid $13.2 million in cash to settle outstanding principal and accrued interest, and on February 7, 2018 issued 253,000 shares of the Company’s common stock to the holders of the 3.50% Convertible Notes. The total number of shares was determined using a three-day volume weighted averaging price period and based on a prescribed formula in the Exchange Agreements. As a result, the 3.50% Convertible Notes were repaid in full in fiscal year 2018. 3.50% Series A Convertible Senior Notes due February 2018 In April 2014, the Company issued 3.50% Series A Convertible Senior Notes due 2018 (the “3.50% Series A Convertible Notes”) under an indenture between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee. Holders of the 3.50% Series A Convertible Notes were entitled to convert their notes at any time on or after November 1, 2017 until the close of business on the business day immediately preceding the maturity date of February 1, 2018. The initial conversion rate was 187.6877 shares of the Company’s common stock per $1,000 principal amount, which represented an initial conversion price of approximately $5.33 per share of the Company’s common stock. Pursuant to the original settlement terms, the Company made an irrevocable net share settlement election and paid cash for principal plus accrued interest upon maturity to holders who did not elect to convert. Prior to maturity, one note holder elected to convert its notes and receive a combination of cash and shares at settlement. The number of shares was determined based on a prescribed formula in the indenture. On February 1, 2018, the Company paid an aggregate amount of $27.0 million in cash and delivered 1,252 shares of its common stock to settle the 3.50% Series A Convertible Notes. As a result, the 3.50% Series A Convertible Notes were repaid in full in fiscal year 2018. 3.75% Convertible Senior Notes due July 2022 In August 2017, the Company issued $85.0 million aggregate principal amount of its 3.75% Convertible Senior Notes due 2022 (the “3.75% Convertible Notes”) under an indenture between the Company and The Bank of New York Mellon Trust Company, N.A., as trustee. $53.0 million aggregate principal amount of the 3.75% Convertible Notes were issued to certain holders of the Company’s outstanding 3.50% Convertible Notes and 3.50% Series A Convertible Notes (together, the “Existing Notes”) in exchange for approximately $47.0 million aggregate principal amount of the Existing Notes (the “Exchange”), and $32.0 million aggregate principal amount of the 3.75% Convertible Notes were issued to certain other qualified new investors for cash. The net proceeds of the cash issuance were used to repurchase approximately $28.0 million of Existing Notes (the “Repurchase”). Holders of the 3.75% Convertible Notes may convert their notes at any time on or after April 15, 2022 until the close of the business day immediately preceding the maturity date. Prior to April 15, 2022, holders of the 3.75% Convertible Notes may convert their notes only under certain circumstances. Upon conversion, the Company will have the right to pay cash, or deliver shares of common stock of the Company or a combination thereof, at the Company’s election. The initial conversion rate is 174.8252 shares of the Company’s common stock per $1,000 principal amount (which represents an initial conversion price of approximately $5.72 per share of the Company’s common stock). The conversion rate, and thus the conversion price, is subject to adjustment as further described below. Holders of the 3.75% Convertible Notes who convert their notes in connection with a “make-whole fundamental change,” as defined in the indenture, may be entitled to a make-whole premium in the form of an increase in the conversion rate. Additionally, in the event of a “fundamental change,” as defined in the indenture, holders of the 3.75% Convertible Notes may require the Company to purchase all or a portion of their note at a fundamental change repurchase price equal to 100% of the principal amount of the 3.75% Convertible Notes, plus accrued and unpaid interest, if any, to, but not including, the fundamental change repurchase date. As of March 31, 2019, $85.0 million of aggregate principal amount was outstanding. Revolving Credit Facility On June 14, 2017, the Company entered into a credit and security agreement with a lender (the “Credit Agreement”). The Credit Agreement provides the Company with a revolving credit facility in the initial amount of $52.0 million (the “Revolving Credit Facility”). Availability for borrowings under the Revolving Credit Facility is subject to a borrowing base that is calculated as a function of the value of the Company’s eligible accounts receivable and eligible inventory, and the Company is required to maintain a minimum drawn balance of at least 30% of such availability. Interest on the borrowings under the Revolving Credit Facility is payable monthly in arrears at an annual interest rate of reserve-adjusted, 90-day LIBOR plus 4.50% and had an initial maturity date of June 14, 2021. In December 2017, concurrently with the Term Loan Agreement described below, the Company entered into an amendment to the Credit Agreement (the “Amendment” and, collectively with the Credit Agreement, the “Amended Credit Agreement”). The Amendment reduced the maximum borrowings under the Revolving Credit Facility to $32.0 million and extended the maturity date of the Revolving Credit Facility to December 15, 2022. The Amended Credit Agreement contains restrictions and covenants applicable to the Company. Among other requirements, the Company may not permit the Fixed Charge Coverage Ratio (as defined in the Amended Credit Agreement) to be less than a certain specified ratio for each fiscal quarter during the term of the Revolving Credit Facility. In addition, the Amended Credit Agreement contains customary restrictive covenants that limit, among other things, the ability of the Company and its subsidiaries to (i) incur additional indebtedness, (ii) incur liens on their property, (iii) pay dividends or make other distributions, (iv) sell their assets, (v) make certain loans or investments, (vi) merge or consolidate, (vii) voluntarily repay or prepay certain indebtedness and (viii) enter into transactions with affiliates, in each case subject to certain exceptions. In July 2018, the Company amended both the Amended Credit Agreement and the Term Loan Agreement (as defined below). The amendments provide for, among other things, adjustments to the Fixed Charge Coverage Ratio such that in the case of the Defined Periods (as defined in the Amended Credit Agreement and the Term Loan Agreement) for (a) the fiscal quarter ending June 30, 2018 as well as (b) the fiscal quarter ending March 31, 2019, the Fixed Charge Coverage Ratio is not less than 0.75 to 1.00 and 0.50 to 1.00, respectively. Other significant terms remain unchanged. In December 2018, the Company further amended the Amended Credit Agreement (“Amendment 3”) which, among other things, updated the calculation of the deferred revolving loan origination fee such that it is based on the amount of time elapsed from the effective date of Amendment 3. Other significant terms remain unchanged. The Company was in compliance with the covenants under the Amended Credit Agreement as of March 31, 2019. As of March 31, 2019, approximately $30.5 million of aggregate principal amount was outstanding under the Revolving Credit Facility, and $1.2 million of unamortized debt costs associated with the Debt Agreement was included in other assets on the condensed consolidated balance sheet. Term Loan In December 2017, the Company entered into a credit and security agreement with a lender (the “Term Loan Agreement”). The Term Loan Agreement provides for an initial term loan of $40.0 million with an additional tranche of $20.0 million available through December 31, 2018, if specified conditions are met (the “Term Loan”). In connection with the Amendment, the Company used a portion of the net proceeds from the initial advance to repay a portion of the outstanding borrowings under the Revolving Credit Facility. Interest on the Term Loan is payable monthly in arrears at an annual interest rate of 6.75% plus 90-day LIBOR. The Term Loan Agreement matures December 15, 2022 and, if prepaid, has fees equal to 3%, 2%, and 1% of the prepayment amount if such termination occurs within the first year, the second year, and the third year of funding, respectively. The term of the loan is 60 months with interest only for the first 24 months followed by straight-line amortization of principal for the remaining months. At the Company’s option, the interest-only period can be extended an additional 12 months, provided revenues for the previous four quarters is $400 million or greater. In addition, the Company will pay an annual administrative fee of 0.25% and a final payment of 4.0% of the Term Loan amount. In December 2018, the Company drew an additional $5.0 million under the Term Loan Agreement and in connection therewith entered into the second amendment to the Term Loan Agreement (“Amendment 2”) which, among other things, (i) extended the term loan tranche 2 commitment termination date for the remaining $15.0 million unfunded commitment from December 31, 2018 to June 30, 2019; (ii) provided that term loan tranche 2 may be drawn in two separate advances; and (iii) updated the calculation of the prepayment fee such that it is based on the amount of time elapsed from the effective date of Amendment 2. The Company was in compliance with the covenants under the Term Loan Agreement as of March 31, 2019. As of March 31, 2019, $45.0 million of aggregate principal amount was outstanding.

Segment Information The Company operates in one reportable segment (oncology systems group), which develops, manufactures and markets proprietary medical devices used in radiation therapy and radiosurgery for the treatment of cancer patients. The Company’s Chief Executive Officer, its Chief Operating Decision Maker, reviews financial information presented on a consolidated basis for purposes of making operating decisions and assessing financial performance. The Company does not assess the performance of its individual product lines on measures of profit or loss, or asset-based metrics. Disaggregation of Revenues The Company disaggregates its revenues from contracts by geographic region, as the Company believes this best depicts how the nature, amount, timing and uncertainty of revenues and cash flows are affected by economic factors. Additionally, the Company typically recognizes revenue at a point in time for product revenue and recognizes revenue over time for service revenue. The following tables present net revenue and long-lived asset information based on geographic region.

Income Tax Disclosure [Abstract]
Income Tax	Note 14. Income Tax On a quarterly basis, the Company provides for income taxes based upon an estimated annual effective income tax rate. The Company recognized an income tax expense of $0.2 million and $0.6 million for the three months ended March 31, 2019 and March 31, 2018, respectively. The decrease in income tax expense was due to recognition of an income tax benefit of approximately $0.4 million in the third quarter of this fiscal year as a result of the final assessment from the Swiss authorities for the fiscal year 2017. The Company recognized an income tax expense of $1.2 million and $1.3 million for the nine months ended March 31, 2019 and 2018, respectively. The decrease in income tax expense was driven by lower annual effective income tax rate on foreign profits for the nine months ended March 31, 2019 as compared to the same period in the prior fiscal year. The Tax Act has a requirement that certain income earned by controlled foreign corporations (“CFCs”) must be included currently in the gross income of the CFC’s U.S. shareholder. The income required to be included in gross income is referred to as global intangible low tax income (“GILTI”) and is as defined under Internal Revenue Code (“IRC”) Section 951A as is the excess of the shareholder’s net CFC tested income over the net deemed tangible income return. The GILTI inclusion amount is expected to be fully absorbed by net operating losses and is not expected to cause the Company to be in a U.S. taxable income position for fiscal year 2019. The Company has made a policy decision to record GILTI tax as a current-period expense when incurred. In addition to the GILTI provision, the Tax Act also enacted the Base Erosion and Anti-Abuse Tax (“BEAT”). The BEAT minimum tax under IRC Section 59A is applicable to the extent that the BEAT tax amount is greater than the regular corporate tax for a given year. This tax is applicable to companies with prior 3-year average annual gross receipts exceeding $500 million. The Company does not currently meet this threshold since its current average annual gross receipts are less than $500 million.

Joint Venture	Note 15. Joint Venture In January 2019, the Company’s wholly-owned subsidiary, Accuray Asia Limited (“Accuray Asia”), entered into an agreement with CNNC High Energy Equipment (Tianjin) Co., Ltd. (the “CIRC Subsidiary”), a wholly-owned subsidiary of China Isotope & Radiation Corporation, to form a joint venture, CNNC Accuray (TianJin) Medical Technology Co. Ltd. (the “JV”), to manufacture and sell radiation oncology systems in China. Accuray Asia initially has a 49% ownership interest in the joint venture and the CIRC Subsidiary initially has a 51% ownership interest in the joint venture. The JV was granted a business license in April 2019. For the three and nine months ended March 31, 2019, no JV business activities took place as the business license was not yet issued. In exchange for the initial 49% equity interest in the JV, the Company, through Accuray Asia, expects to make its initial capital contributions to the JV by December 31, 2019 in the form of in-kind contributions consisting of components for two full radiation oncology systems from the Company’s inventory. Any remaining amount of capital contributions due, if not satisfied by such in-kind contributions, will be made by the Company, through Accuray Asia, in accordance with the schedule set by the board of directors of the JV. The Company is assessing the accounting treatment of its investment in the JV and expects to apply the equity method of accounting to the ownership interest in the JV as it has the ability to exercise significant influence over the JV but lacks controlling financial interest and is not the primary beneficiary. The Company will recognize the 49% proportionate share of the JV income or loss on a one-quarter lag due to the timing of the availability of the JV’s financial records.

Revenue Recognition	Revenue Recognition The Company’s revenue is primarily derived from sales of CyberKnife and TomoTherapy Systems and services, which include post-contract customer support (“PCS”), installation services, training and other professional services. The Company has a contract with a customer when there is approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. The Company's revenues are measured based on consideration specified in the contract with each customer, net of any sales incentives and amounts collected on behalf of third parties such as sales taxes, excise taxes, and VAT. The majority of the Company's revenue arrangements consists of multiple performance obligations, which can include system, upgrades, installation, training, services, construction, and consumables. For bundled arrangements, the Company accounts for individual products and services separately if a product or service is separately identifiable from other items in the bundled package and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company’s products are generally not sold with a right of return, and the Company’s contracts generally provide a fixed transaction price. However, the Company from time to time offers variable consideration such as volume discounts. The Company also from time to time offers extended payment terms beyond one year, trade-in allowance for old systems, and commissions or other forms of payment to customers. The Company applied the practical expedient to not adjust for a significant financing component if the gap between payment and delivery was expected, at the contract inception, to be less than one year. The stand-alone selling price (“SSP”) of performance obligations is determined based on observable prices at which the Company separately sells the products and services. If the SSP is not directly observable, then the Company will estimate the SSP considering market conditions, entity-specific factors, and information about the customer or class of customer that is reasonably available. The SSP is generally assessed as a percentage of the list price. The contract consideration allocation is based on the SSP at contract inception. The consideration (net of any discounts) is allocated among separate products and services in a bundle based on their individual SSP. For contract modifications that add additional goods or services or changes pricing, the most recent SSP is used for allocation to the remaining performance obligations. The Company recognizes revenue for certain performance obligations at the point in time when control is transferred, such as delivery of products. The Company recognizes revenue for certain other performance obligations over a period of time as control of the goods or services is transferred, such as PCS and construction contracts. The Company recognizes an asset for the incremental costs of obtaining a contract with a customer if the Company expects the benefit of those costs to be longer than one year. The Company capitalizes incremental contract acquisition costs, and amortizes such costs over the period which the Company expects to benefit, which may extend beyond the initial contract term. Most of the Company’s contract costs are associated with its internal sales force compensation program and a portion of its employee bonus program. The Company amortizes capitalized bonuses and a portion of sales commissions over a period of five years commencing upon the initial transfer of control of the system to the customer. The pattern of amortization is commensurate with the pattern of transfer of control of the performance obligations to the customer. The Company elected to use the practical expedient in ASC 340-40-25-4 and expense as incurred commissions related to service renewals and upgrades because the contract term is less than a year.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606 The Company completed its assessment of the impact this guidance has on its consolidated financial statements and related disclosures. Based on that assessment, the Company concluded the significant impact areas were the capitalization and amortization of incremental costs of obtaining a contract, primarily related to certain bonuses and sales commissions, change in SSP and the removal of software revenue recognition rules along with the elimination of revenue deferral for cash basis customers. Under the new standards, the Company capitalizes incremental contract acquisition costs, such as certain bonuses and sales commissions, and amortizes such costs over the period which the Company benefits, as estimated by management, which may extend beyond the initial contract term. The Company amortizes capitalized bonuses and sales commissions over a period of five years commencing upon the initial transfer of control of the system to the customer. The pattern of amortization is commensurate with the pattern of transfer of control of the performance obligations to the customer. The Company elected to use the practical expedient in ASC 340-40-25-4 and expense commissions related to service renewals and upgrades with a renewal contract term of one year or less as incurred. The Company recorded a net reduction to opening accumulated deficit of $5.1 million, net of tax, as of July 1, 2018 due to the cumulative impact of adopting ASC 606, with the impact primarily related to the deferral of incremental costs to obtain contracts. Under ASC 606, product revenue for direct sales are accelerated to reflect transfer of control upon delivery while an element of installation is deferred until performed. Prior to the adoption of ASC 606, the Company deferred revenue until installation had occurred. The revenue recognition method for indirect sales and service revenues is unchanged under the new guidance. Refer to Note 3, Revenue,
