Debt Disclosure [Abstract]
Financing Arrangements	Note 4 – Financing Arrangements (a) Loan and Security Agreement – Western Alliance Bank On March 30, 2020, the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with Western Alliance Bank (the “Bank”) that provided an initial term loan (“Term Loan”) facility of $7.0 million and a $5.0 million revolving line of credit. The Loan Agreement was amended effective June 16, 2020. The Loan Agreement, as amended, requires the Company to either (i) meet a minimum revenue covenant based on certain testing periods (to be agreed upon and set in good faith by the Company and the Bank) or (ii) maintain a ratio of unrestricted cash at the Bank to aggregate indebtedness owed to the Bank of at least 1.25 to 1.00 (the “Unrestricted Cash Covenant”). In accordance with the amendment, the Company and the Bank agreed that if there is not a minimum revenue covenant in place, the Company shall, at all times, be required to comply with the Unrestricted Cash Covenant. As of March 31, 2021, the Company was in compliance with the Unrestricted Cash Covenant . If at any point the Company is not in compliance with certain covenants under the Loan Agreement and is unable to obtain an amendment or waiver, such noncompliance may result in an event of default under the Loan Agreement, which could permit acceleration of the outstanding indebtedness and require the Company to repay such indebtedness before the scheduled due date. The Company was required, periodically in the past, to seek modifications from its prior lender to avoid non-compliance Interest in arrears on the Term Loan began to be repaid on April 1, 2020 and will continue to be paid on the first of each successive month thereafter until the principal repayment starts. Commencing on the principal repayment date March 1, 2022 and continuing on the first day of each month thereafter, the Company will make equal monthly payments of principal, together with applicable interest in arrears, to the Bank. The interest rate is set at 1% above the Prime Rate, which is defined in the Loan Agreement as the greater of 4.25% or the Prime Rate published in the Money Rates section of the Western Edition of the Wall Street Journal. The Prime Rate as of March 31, 2020 was 3.25%. The Company has the option to prepay all, but not less than all, of the Term Loan advanced by the Bank under the Loan Agreement. The Company prepayment is subject to payment of (1) all outstanding principal of the Term Loan plus accrued and unpaid interest thereon through the prepayment date, (2) the final payment ($122,500 or 1.75% of the original loan amount), (3) a 2% of principal if prepaid after March 30, 2021 but before June 30, 2022, or 1% of principal if prepaid after March 30, 2022) plus (4) all other obligations that are due and payable, including the Bank’s expenses and interest at the default rate with respect to any past due amounts. Obligations to the Bank under the Loan Agreement are secured by a first priority security interest in the Company’s assets, except for certain permitted liens that have priority to the Bank’s security interest by operation of law. In connection with the Loan Agreement, the Company incurred approximately $141,000 of closing costs. The closing costs have been deduced from the carrying value of the debt and will be amortized through March 30, 2022, the maturity date of the Term Loan. The maturity date of the revolving loan is March 30, 2022 and there was no outstanding amount as of March 31, 2021. On April 27, 2021, the Company repaid its obligations in the aggregate amount of $7,354,283 under and terminated the Loan Agreement with the Bank, and its collateral securing the facility was released. (b) Loan and Security Agreement – Silicon Valley Bank On August 7, 2017, the Company entered into a Loan and Security Agreement, which has since been modified several times through November 1, 2019 (as amended, the “SVB Loan Agreement”), with Silicon Valley Bank that provided an initial term loan facility of $6.0 million and a $4.0 million revolving line of credit. On March 30, 2020, the Company elected to repay all outstanding obligations (including accrued interest) and retire the SVB Loan Agreement. The Company accounted for this repayment and retirement as an extinguishment of the SVB Loan Agreement. In addition to the outstanding principal and accrued interest, the Company was required to pay the $510,000 final payment, a termination fee of $114,000 and other costs totaling $10,000. The Company also wrote off unamortized original closing costs as of the extinguishment date. In M 2020 the (c) Convertible Debentures On December 20, 2018, the Company entered into a Securities Purchase Agreement (the “SPA”) with certain institutional and accredited investors (the “Investors”), including, but not limited to, all directors and executive officers of the Company at the time, pursuant to which the Investors purchased unsecured subordinated convertible debentures (the “Convertible Debentures”) with an aggregate principal amount of approximately $7.0 million in a private placement. On February 21, 2020 (the “Conversion Date”), the conditions permitting a forced conversion were met, and the Company elected to exercise its forced conversion right under the terms of the Convertible Debentures. As a result of this election, all of the outstanding Convertible Debentures were converted, at a conversion price of $4.00 per share, into 1,742,500 shares of the Company’s common stock. In accordance with the make-whole provisions in the Convertible Debentures, the Company also issued an additional 76,966 shares of its common stock. The make-whole amount represented the total interest which would have accrued through the maturity date of the Convertible Debentures, less the amounts previously paid, totaling $697,000. The conversion prices related to the make-whole amount were dependent on whether the Investors were related parties or unrelated third parties. Accounting Considerations and Fair Value Measurements Related to the Convertible Debentures The Company had previously elected to make a one-time, irrevocable As of the December 31, 2019 valuation and the prior measurement dates, the Company utilized a Monte Carlo simulation model to estimate the fair value of the Convertible Debentures. The simulation model was designed to capture the potential settlement features of the Convertible Debentures, in conjunction with simulated changes in the Company’s stock price and the probability of certain events occurring. The simulation utilized 100,000 trials or simulations to determine the estimated fair value. The simulation utilized the assumptions that if the Company was able to exercise its forced conversion right (if the requirements to do so were met), that it would do so in 100% of such scenarios. Additionally, if an event of default occurred during the simulated trial (based on the Company’s probability of default), the Investors would opt to redeem the Convertible Debentures in 100% of such scenarios. If neither event occurred during a simulated trial, the simulation assumed that the Investor would hold the Convertible Debentures until the maturity date. The value of the cash flows associated with each potential settlement were discounted to present value in each trial based on either the risk-free rate (for an equity settlement) or the effective discount rate (for a redemption or cash settlement). The Company also recorded a final adjustment to the Convertible Debentures based on their fair value on the Conversion Date, just prior to the forced conversion being completed. Given that the Company’s prior simulation model included the assumption that the Company would elect to force conversion in 100% of scenarios when the requirements were met, the final valuation was based on the actual results of the forced conversion. As such, the Company based the final fair value adjustment to the Convertible Debentures just prior to conversion on the number of shares of common stock that were issued to the Investors upon conversion and the fair value of the Company’s common stock as of the Conversion Date. The Company notes that the key inputs to the valuation models that were utilized to estimate the fair value of the Convertible Debentures included: Input December 31, 2019 February 21, 2020 Company’s stock price $ 7.77 $ 11.64 Conversion price 4.00 4.00 Remaining term (years) 1.97 0.00 Equity volatility 49.00 % N/A Risk free rate 1.57 % N/A 1 Probability of default event 0.45 % N/A 1 Utilization of Forced Conversion (if available) 100.00 % 100.00 % 1 Exercise of Default Redemption (if available) 100.00 % N/A 1 Effective discount rate 18.52 % N/A 1 Represents a Level 3 unobservable input, as defined in Note 8 - Fair Value Measurements, below. The Company’s stock price was based on the closing stock price on the valuation date. The conversion price was based on the contractual conversion price included in the SPA. The remaining term was determined based on the remaining time period to maturity of the Convertible Debentures, or remaining term under the expectation of the Company’s election of its forced conversion right. The Company’s equity volatility estimate was based on the Company’s historical equity volatility, the Company’s implied and observed volatility of option pricing, and the historical equity and observed volatility of option pricing for a selection of public companies. The risk-free rate was determined based on U.S. Treasury securities with similar terms. The probability of the occurrence of a default event was based on Bloomberg’s 1-year The utilization of the forced conversion right and the default redemption right was based on management’s best estimate of both features being exercised upon the occurrence of the related contingent events. The effective discount rate utilized at the December 31, 2019 valuation date was based on yields on CCC-rated The fair value and principal value of the Convertible Debentures as of December 31, 2019 and the Conversion Date was as follows (in thousands): Convertible Debentures December 31, 2019 February 21, 2020 Fair value, in accordance with fair value option $ 13,642 $ 21,164 Principal value outstanding $ 6,970 $ 6,970 In February 2020 t million for period through the Conversion Date which is described in the additional fair value disclosures related to the Convertible Debentures in Note . Upon the consummation of the forced conversion, the Company issued 1,816,466 shares of common stock with a fair value of approximately $21.2 million, which was reclassified to stockholders’ equity.

Lease Commitments	Note 5 – Lease Commitments Under ASC 842, “Leases” (“ASC 842”), the Company determines if an arrangement contains a lease at inception. A lease is a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment (i.e., an identified asset) for a period of time in exchange for consideration. Leases are classified as either operating leases or financing leases. At lease inception, the Company recognizes a lease liability equal to the present value of the remaining lease payments, and a right of use asset equal to the lease liability, subject to certain adjustments, such as for lease incentives. The Company uses its incremental borrowing rate to determine the present value of the lease payments. The Company determines the incremental borrowing rates for its leases by applying its applicable, fully collateralized borrowing rate, with adjustment as appropriate for the lease term. The lease term at the lease commencement date is determined based on the non-cancellable Right-of-use non-lease non-lease ASC 842 includes a number of reassessment and re-measurement re-measurement right-of-use Certain of the Company’s leases include variable lease costs to reimburse the lessor for real estate tax and insurance expenses, and certain non-lease non-lease . Components of Leases: The Company has leases for office space and office equipment.

Commitments and Contingencies	Note 7 – Commitments and Contingencies Other Commitments The Company is obligated to pay approximately $4.1 million for firm purchase obligations to suppliers for future product and service deliverables and $0.5 million for minimum royalty obligations. Litigation In December 2016, the Company entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) with Invivo Corporation (“Invivo”). In accordance with the Asset Purchase Agreement, the Company sold to Invivo all right, title and interest to certain intellectual property relating to the Company’s VersaVue Software and DynaCAD product and related assets for $3.2 million. The Company closed the transaction on January 30, 2017 less a holdback reserve of $350,000 (the “Escrowed Amount”) for net proceeds of approximately $2.9 million. On September 5, 2018, third-party Yeda Research and Development Company Ltd. (“Yeda”), filed a complaint (the “Complaint”) against the Company and Invivo in the United States District Court for the Southern District of New York, captioned Yeda Research and Development Company Ltd. v. iCAD, Inc. and Invivo Corporation, Case No. 1:18-cv-08083-GBD, related to the Company’s sale of the VersaVue software and DynaCAD product under the Asset Purchase Agreement. Yeda alleged, among other things, that the Company infringed upon Yeda’s source code, which was originally licensed to the Company, by using it in the products that the Company sold to Invivo and that it is entitled to damages that could include, among other things, profits relating to the sales of these products On April 13, 2021, the Company and Yeda entered into a Settlement and Release Agreement (the “Settlement Agreement”) whereby the Company furnished to Yeda a one-time cash payment of and received a full, non-conditional release from Yeda of any and all claims related to the Complaint and the subject of the Complaint. Neither the Company nor Invivo acknowledged any wrongdoing at any point in connection with the Complaint or the subject matter thereof. The Escrowed Amount was reserved, in part, to cover any legal expenses related to the Asset Purchase Agreement and the transactions contemplated therein. The remaining balance of the Escrowed Amount following such expenses is due and payable to the Company in accordance with the terms of the Asset Purchase Agreement. However, the Company is unaware of the amount Invivo may claim it is entitled to of the Escrowed Amount, if any, under the Asset Purchase Agreement. The Company may be a party to various legal proceedings and claims arising out of the ordinary course of its business. Although the final results of all such matters and claims cannot be predicted with certainty, the Company currently believes that there are no current proceedings or claims pending against it the ultimate resolution of which would have a material adverse effect on its financial condition or results of operations. However, should the Company fail to prevail in any legal matter or should several legal matters be resolved against the Company in the same reporting period, such matters could have a material adverse effect on the Company’s operating results and cash flows for that particular period. The Company may be a party to certain actions that have been filed against the Company which are being vigorously defended. The Company has determined that potential losses in these matters are neither probable or reasonably possible at this time. In all cases, at each reporting period, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under ASC 450, “Contingencies.” Legal costs are expensed as incurred.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 8 - Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset • Level 1 - Quoted prices in active markets for identical assets or liabilities. • Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, and notes payable and convertible debentures. Due to their short-term nature and market rates of interest, the carrying amounts of the financial instruments (except the Convertible Debentures, which were measured at fair value in accordance with the fair value option election) approximated fair value as of February 21, 2020 and December 31, 2019. The Company’s assets and liabilities that are measured at fair value on a recurring basis include the Company’s money market accounts and Convertible Debentures. The money market accounts are included in cash and cash equivalents in the accompanying consolidated balance sheet and are considered a Level 1 measurement as they are valued at quoted market prices in active markets. The Convertible Debentures were recorded as a separate component of the Company’s consolidated balance sheet and are considered a Level 3 measurement due to the utilization of significant unobservable inputs in their valuation. See Note 4(b) for a discussion of these fair value measurements. The following table sets forth the Company’s assets and liabilities which are measured at fair value on a recurring basis by level within the fair value hierarchy (in thousands).

Income Taxes	Note 9 - Income Taxes The Coronavirus Aid, Relief, and Economic Security Act was enacted on March 27, 2020 and did not have a material impact on the Company’s provision for income taxes for the three months ended March 31, 2021. The Company recorded an income tax provision of $0 for the three months ended March 31, 2021, and $26,000 for the three months ended March 31, 2020. The Company adopted ASU 2019-12 as of January 1, 2021, in accordance with this provision non-income and state franchise taxes are now classified as a component of operating expenses in General and Administrative expense. Income based tax expense will continue to be recognized as tax expense in the Consolidated Financial Statements. Tax expense for three months ended March 31, 2020 represent non-income and state franchise tax, however the expense was not reclassified to operating expenses in accordance with ASU 2019-12. The Company had no material unrecognized tax benefits and a deferred tax liability of approximately $4,000 related to tax amortizable goodwill. No other adjustments were required under ASC 740, “Income Taxes.” The Company does not expect that its unrecognized tax benefits will materially increase within the next 12 months. The Company did not recognize any interest or penalties related to uncertain tax positions at March 31, 2021. The Company files United States federal income tax returns and income tax returns in various states and local jurisdictions. The Company’s three preceding tax years remain subject to examination by federal and state tax authorities. In addition, because the Company has net operating loss carry-forwards, the Internal Revenue Service and state jurisdictions are permitted to audit earlier years and propose adjustments up to the amount of net operating loss generated in those years. The Company is not currently under examination by any federal or state jurisdiction for any tax years.

Goodwill

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Note 10 - Goodwill The Company tests goodwill for impairment on an annual basis and between annual tests if events and circumstances indicate it is more likely than not that the fair value of the reporting unit is less than its carrying value. There were no impairment indicators present as of March 31, 2021. Factors the Company considers important, which could trigger an impairment of such asset, include the following: • significant underperformance relative to historical or projected future operating results; • significant changes in the manner or use of the assets or the strategy for the Company’s overall business; • significant negative industry or economic trends; • significant decline in the Company’s stock price for a sustained period; and • a decline in the Company’s market capitalization below net book value. The Company would record an impairment charge when such assessment indicates that the fair value of a reporting unit is less than the carrying value. In evaluating potential impairments outside of the annual measurement date, judgment is required in determining whether an event has occurred that may impair the value of goodwill or intangible assets. The Company utilizes either discounted cash flow models or other valuation models, such as comparative transactions and market multiples, to determine the fair value of reporting units. The Company makes assumptions about future cash flows, future operating plans, discount rates, comparable companies, market multiples, purchase price premiums and other factors in those models. Different assumptions and judgment determinations could yield different conclusions that would result in an impairment charge to income in the period that such change or determination was made. The Company determines the fair values for each reporting unit using a weighting of the income approach and the market approach. For purposes of the income approach, fair value is determined based on the present value of estimated future cash flows, discounted at an appropriate risk adjusted rate. The Company uses internal forecasts to estimate future cash flows and includes estimates of long-term future growth rates based on its most recent views of the long-term forecast for each segment. Accordingly, actual results can differ from those assumed in the Company’s forecasts. Discount rates are derived from a capital asset pricing model and by analyzing published rates for industries relevant to the Company’s reporting units to estimate the cost of equity financing. The Company uses discount rates that are commensurate with the risks and uncertainty inherent in the respective businesses of its reporting units and in the Company’s internally developed forecasts. In the market approach, the Company uses a valuation technique in which values are derived based on market prices of publicly traded companies with similar operating characteristics and in similar industries. A market approach allows for comparison to actual market transactions and multiples. It can be somewhat limited in its application because the population of potential comparable publicly-traded companies can be limited due to differing characteristics of the comparative business and the Company, as well as the fact that market data may not be available for divisions within larger conglomerates or non-public The Company corroborates the total fair values of the reporting units using a market capitalization approach; however, this approach cannot be used to determine the fair value of each reporting unit. The blend of the income approach and market approach is more closely aligned to the business profile of the Company, including markets served and products available. In addition, required rates of return, along with uncertainties inherent in the forecast of future cash flows, are reflected in the selection of the discount rate. In addition, under the blended approach, reasonably likely scenarios and associated sensitivities can be developed for alternative future states that may not be reflected in an observable market price. The Company will assess each valuation methodology based upon the relevance and availability of the data at the time the valuation is performed and weights the methodologies appropriately. The Company has two operating segments, Detection and Therapy, as further discussed in Note 12 below. A rollforward of goodwill activity by reportable segment is as follows (in thousands): Consolidated Detection Therapy Total Accumulated Goodwill $ 47,937 $ — $ — $ 47,937 Accumulated impairment (26,828 ) — — (26,828 ) Fair value allocation (21,109 ) 7,663 13,446 — Acquisition of DermEbx and Radion — — 6,154 6,154 Acquisition measurement period adjustments — — 116 116 Acquisition of VuComp — 1,093 — 1,093 Sale of MRI assets — (394 ) (394 ) Impairment — — (19,716 ) (19,716 ) Balance at December 31, 2020 and March 31, 2021 — 8,362 — 8,362

Property, Plant and Equipment [Abstract]
Long-lived assets	Note 11 – Long-lived assets The Company assesses long-lived assets for impairment if events and circumstances indicate it is more likely than not that the fair value of the asset group is less than its carrying value. There is no set interval or frequency for recoverability evaluation. Rather, the determination of when, if at all, an asset (or asset group) is evaluated for recoverability is based on “events and circumstances.” The following factors are examples of events or changes in circumstances that indicate the carrying amount of an asset (or asset group) may not be recoverable and thus is to be evaluated for recoverability. • A significant decrease in the market price of a long-lived asset (or asset group); • A significant adverse change in the extent or manner in which a long-lived asset (or asset group) is being used or in its physical condition; • A significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset (or asset group), including an adverse action or assessment by a regulator; • An accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset (or asset group); and • A current operating period, or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset (or asset group). The Company determined there were no such triggering events in the quarter ended March 31, 2021. If the carrying amount of an asset or asset group (in use or under development) is evaluated and found not to be fully recoverable (e.g., the carrying amount exceeds the estimated gross, undiscounted cash flows from use and disposition), then an impairment loss must be recognized. The impairment loss is measured as the excess of the carrying amount over the fair value of the asset (or asset group). The Company determined the “Asset Group” of the Company to be the assets of the Therapy segment and the Detection segment, which the Company considers to be the lowest level for which the identifiable cash flows were largely independent of the cash flows of other assets and liabilities. A considerable amount of judgment and assumptions are required in performing the impairment tests, principally in determining the fair value of the asset group and the reporting unit. While the Company believes that its judgments and assumptions are reasonable, different assumptions could change the estimated fair values and, therefore additional impairment charges could be required. Significant negative industry or economic trends, disruptions to the Company’s business, loss of significant customers, inability to effectively integrate acquired businesses, unexpected significant changes or planned changes in use of the assets may adversely impact the assumptions used in the fair value estimates and ultimately result in future impairment charges.

Segment Reporting [Abstract]
Segment Reporting	Note 12 – Segment Reporting Operating segments are defined as components of an enterprise that engage in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker (“CODM”) in deciding how to allocate resources and assess performance. The Company’s CODM is the Chief Executive Officer. Each reportable segment generates revenue from the sale of medical equipment and related services and/or sale of supplies. The Company has determined there are two segments, Detection and Therapy. The Detection segment consists of the Company’s advanced image analysis and workflow products, and the Therapy segment consists of the Company’s radiation therapy products, “Axxent,” and related services. The primary factors used by the Company’s CODM to allocate resources are based on revenues, gross profit, operating income, and earnings or loss before interest, taxes, depreciation, amortization, and other specific and non-recurring The Company does not track assets by operating segment and the Company’s CODM does not use asset information by segment to allocate resources or make operating decisions.

Litigation	Litigation In December 2016, the Company entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) with Invivo Corporation (“Invivo”). In accordance with the Asset Purchase Agreement, the Company sold to Invivo all right, title and interest to certain intellectual property relating to the Company’s VersaVue Software and DynaCAD product and related assets for $3.2 million. The Company closed the transaction on January 30, 2017 less a holdback reserve of $350,000 (the “Escrowed Amount”) for net proceeds of approximately $2.9 million. On September 5, 2018, third-party Yeda Research and Development Company Ltd. (“Yeda”), filed a complaint (the “Complaint”) against the Company and Invivo in the United States District Court for the Southern District of New York, captioned Yeda Research and Development Company Ltd. v. iCAD, Inc. and Invivo Corporation, Case No. 1:18-cv-08083-GBD, related to the Company’s sale of the VersaVue software and DynaCAD product under the Asset Purchase Agreement. Yeda alleged, among other things, that the Company infringed upon Yeda’s source code, which was originally licensed to the Company, by using it in the products that the Company sold to Invivo and that it is entitled to damages that could include, among other things, profits relating to the sales of these products On April 13, 2021, the Company and Yeda entered into a Settlement and Release Agreement (the “Settlement Agreement”) whereby the Company furnished to Yeda a one-time cash payment of and received a full, non-conditional release from Yeda of any and all claims related to the Complaint and the subject of the Complaint. Neither the Company nor Invivo acknowledged any wrongdoing at any point in connection with the Complaint or the subject matter thereof. The Escrowed Amount was reserved, in part, to cover any legal expenses related to the Asset Purchase Agreement and the transactions contemplated therein. The remaining balance of the Escrowed Amount following such expenses is due and payable to the Company in accordance with the terms of the Asset Purchase Agreement. However, the Company is unaware of the amount Invivo may claim it is entitled to of the Escrowed Amount, if any, under the Asset Purchase Agreement. The Company may be a party to various legal proceedings and claims arising out of the ordinary course of its business. Although the final results of all such matters and claims cannot be predicted with certainty, the Company currently believes that there are no current proceedings or claims pending against it the ultimate resolution of which would have a material adverse effect on its financial condition or results of operations. However, should the Company fail to prevail in any legal matter or should several legal matters be resolved against the Company in the same reporting period, such matters could have a material adverse effect on the Company’s operating results and cash flows for that particular period. The Company may be a party to certain actions that have been filed against the Company which are being vigorously defended. The Company has determined that potential losses in these matters are neither probable or reasonably possible at this time. In all cases, at each reporting period, the Company evaluates whether or not a potential loss amount or a potential range of loss is probable and reasonably estimable under ASC 450, “Contingencies.” Legal costs are expensed as incurred.
Fair Value Measurements	Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset • Level 1 - Quoted prices in active markets for identical assets or liabilities. • Level 2 - Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, accounts payable, and notes payable and convertible debentures. Due to their short-term nature and market rates of interest, the carrying amounts of the financial instruments (except the Convertible Debentures, which were measured at fair value in accordance with the fair value option election) approximated fair value as of February 21, 2020 and December 31, 2019. The Company’s assets and liabilities that are measured at fair value on a recurring basis include the Company’s money market accounts and Convertible Debentures. The money market accounts are included in cash and cash equivalents in the accompanying consolidated balance sheet and are considered a Level 1 measurement as they are valued at quoted market prices in active markets. The Convertible Debentures were recorded as a separate component of the Company’s consolidated balance sheet and are considered a Level 3 measurement due to the utilization of significant unobservable inputs in their valuation. See Note 4(b) for a discussion of these fair value measurements. The following table sets forth the Company’s assets and liabilities which are measured at fair value on a recurring basis by level within the fair value hierarchy (in thousands). Fair Value Measurements as of December 31, 2020 Level 1 Level 2 Level 3 Total Assets Money market accounts $ 27,186 — — $ 27,186 Total Assets $ 27,186 — — $ 27,186 Fair Value Measurements (in thousands) as of March 31, 2021 Level 1 Level 2 Level 3 Total Assets Money market accounts $ 46,907 — — $ 46,907 Total Assets $ 46,907 — — $ 46,907
Income Taxes	The Company recorded an income tax provision of $0 for the three months ended March 31, 2021, and $26,000 for the three months ended March 31, 2020. The Company adopted ASU 2019-12 as of January 1, 2021, in accordance with this provision non-income and state franchise taxes are now classified as a component of operating expenses in General and Administrative expense. Income based tax expense will continue to be recognized as tax expense in the Consolidated Financial Statements. Tax expense for three months ended March 31, 2020 represent non-income and state franchise tax, however the expense was not reclassified to operating expenses in accordance with ASU 2019-12. The Company had no material unrecognized tax benefits and a deferred tax liability of approximately $4,000 related to tax amortizable goodwill. No other adjustments were required under ASC 740, “Income Taxes.” The Company does not expect that its unrecognized tax benefits will materially increase within the next 12 months. The Company did not recognize any interest or penalties related to uncertain tax positions at March 31, 2021. The Company files United States federal income tax returns and income tax returns in various states and local jurisdictions. The Company’s three preceding tax years remain subject to examination by federal and state tax authorities. In addition, because the Company has net operating loss carry-forwards, the Internal Revenue Service and state jurisdictions are permitted to audit earlier years and propose adjustments up to the amount of net operating loss generated in those years. The Company is not currently under examination by any federal or state jurisdiction for any tax years.
Intangibles - Goodwill and Other	The Company tests goodwill for impairment on an annual basis and between annual tests if events and circumstances indicate it is more likely than not that the fair value of the reporting unit is less than its carrying value. There were no impairment indicators present as of March 31, 2021. Factors the Company considers important, which could trigger an impairment of such asset, include the following: • significant underperformance relative to historical or projected future operating results; • significant changes in the manner or use of the assets or the strategy for the Company’s overall business; • significant negative industry or economic trends; • significant decline in the Company’s stock price for a sustained period; and • a decline in the Company’s market capitalization below net book value. The Company would record an impairment charge when such assessment indicates that the fair value of a reporting unit is less than the carrying value. In evaluating potential impairments outside of the annual measurement date, judgment is required in determining whether an event has occurred that may impair the value of goodwill or intangible assets. The Company utilizes either discounted cash flow models or other valuation models, such as comparative transactions and market multiples, to determine the fair value of reporting units. The Company makes assumptions about future cash flows, future operating plans, discount rates, comparable companies, market multiples, purchase price premiums and other factors in those models. Different assumptions and judgment determinations could yield different conclusions that would result in an impairment charge to income in the period that such change or determination was made. The Company determines the fair values for each reporting unit using a weighting of the income approach and the market approach. For purposes of the income approach, fair value is determined based on the present value of estimated future cash flows, discounted at an appropriate risk adjusted rate. The Company uses internal forecasts to estimate future cash flows and includes estimates of long-term future growth rates based on its most recent views of the long-term forecast for each segment. Accordingly, actual results can differ from those assumed in the Company’s forecasts. Discount rates are derived from a capital asset pricing model and by analyzing published rates for industries relevant to the Company’s reporting units to estimate the cost of equity financing. The Company uses discount rates that are commensurate with the risks and uncertainty inherent in the respective businesses of its reporting units and in the Company’s internally developed forecasts. In the market approach, the Company uses a valuation technique in which values are derived based on market prices of publicly traded companies with similar operating characteristics and in similar industries. A market approach allows for comparison to actual market transactions and multiples. It can be somewhat limited in its application because the population of potential comparable publicly-traded companies can be limited due to differing characteristics of the comparative business and the Company, as well as the fact that market data may not be available for divisions within larger conglomerates or non-public The Company corroborates the total fair values of the reporting units using a market capitalization approach; however, this approach cannot be used to determine the fair value of each reporting unit. The blend of the income approach and market approach is more closely aligned to the business profile of the Company, including markets served and products available. In addition, required rates of return, along with uncertainties inherent in the forecast of future cash flows, are reflected in the selection of the discount rate. In addition, under the blended approach, reasonably likely scenarios and associated sensitivities can be developed for alternative future states that may not be reflected in an observable market price. The Company will assess each valuation methodology based upon the relevance and availability of the data at the time the valuation is performed and weights the methodologies appropriately. The Company has two operating segments, Detection and Therapy, as further discussed in Note 12 below. A rollforward of goodwill activity by reportable segment is as follows (in thousands): Consolidated Detection Therapy Total Accumulated Goodwill $ 47,937 $ — $ — $ 47,937 Accumulated impairment (26,828 ) — — (26,828 ) Fair value allocation (21,109 ) 7,663 13,446 — Acquisition of DermEbx and Radion — — 6,154 6,154 Acquisition measurement period adjustments — — 116 116 Acquisition of VuComp — 1,093 — 1,093 Sale of MRI assets — (394 ) (394 ) Impairment — — (19,716 ) (19,716 ) Balance at December 31, 2020 and March 31, 2021 — 8,362 — 8,362
Long-lived assets	The Company assesses long-lived assets for impairment if events and circumstances indicate it is more likely than not that the fair value of the asset group is less than its carrying value. There is no set interval or frequency for recoverability evaluation. Rather, the determination of when, if at all, an asset (or asset group) is evaluated for recoverability is based on “events and circumstances.” The following factors are examples of events or changes in circumstances that indicate the carrying amount of an asset (or asset group) may not be recoverable and thus is to be evaluated for recoverability. • A significant decrease in the market price of a long-lived asset (or asset group); • A significant adverse change in the extent or manner in which a long-lived asset (or asset group) is being used or in its physical condition; • A significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset (or asset group), including an adverse action or assessment by a regulator; • An accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset (or asset group); and • A current operating period, or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset (or asset group). The Company determined there were no such triggering events in the quarter ended March 31, 2021. If the carrying amount of an asset or asset group (in use or under development) is evaluated and found not to be fully recoverable (e.g., the carrying amount exceeds the estimated gross, undiscounted cash flows from use and disposition), then an impairment loss must be recognized. The impairment loss is measured as the excess of the carrying amount over the fair value of the asset (or asset group). The Company determined the “Asset Group” of the Company to be the assets of the Therapy segment and the Detection segment, which the Company considers to be the lowest level for which the identifiable cash flows were largely independent of the cash flows of other assets and liabilities. A considerable amount of judgment and assumptions are required in performing the impairment tests, principally in determining the fair value of the asset group and the reporting unit. While the Company believes that its judgments and assumptions are reasonable, different assumptions could change the estimated fair values and, therefore additional impairment charges could be required. Significant negative industry or economic trends, disruptions to the Company’s business, loss of significant customers, inability to effectively integrate acquired businesses, unexpected significant changes or planned changes in use of the assets may adversely impact the assumptions used in the fair value estimates and ultimately result in future impairment charges.
Segment Reporting	Operating segments are defined as components of an enterprise that engage in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker (“CODM”) in deciding how to allocate resources and assess performance.
