Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Note 1 - Basis of Presentation and Significant Accounting Policies The accompanying condensed consolidated financial statements of iCAD, Inc. and subsidiaries (“iCAD” or the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). In the opinion of management, these unaudited interim condensed consolidated financial statements reflect all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the financial position of the Company at September 30, 2017, the results of operations of the Company for the three and nine month periods ended September 30, 2017 and 2016, and cash flows of the Company for the nine month periods ended September 30, 2017 and 2016. Although the Company believes that the disclosures in these financial statements are adequate to make the information presented not misleading, certain information normally included in the footnotes prepared in accordance with US GAAP has been omitted as permitted by the rules and regulations of the Securities and Exchange Commission (“SEC”). The accompanying financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K Segments The Company reports the results of two segments: Cancer Detection (“Detection”) and Cancer Therapy (“Therapy”). The Detection segment consists of our advanced image analysis and workflow products. The Therapy segment consists of our radiation therapy (“Axxent”) products, physics and management services, development fees, supplies, and fees for the AxxentHub software platform. Revenue Recognition The Company recognizes revenue primarily from the sale of products and from the sale of services and supplies. Revenue is recognized when delivery has occurred, persuasive evidence of an arrangement exists, fees are fixed or determinable and collectability of the related receivable is probable. For product revenue, delivery has occurred upon shipment provided title and risk of loss have passed to the customer. Services and supplies revenue are considered to be delivered as the services are performed or over the estimated life of the supply agreement. The Company recognizes revenue from the sale of its digital, film-based CAD and cancer therapy products and services in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Update No. 2009-13, 2009-13”) No. 2009-14, 2009-14”) 985-605, 985-605”). recognized in accordance with ASC 840 “Leases” (“ASC 840”). For multiple element arrangements, revenue is allocated to all deliverables based on their relative selling prices. In such circumstances, a hierarchy is used to determine the selling price to be used for allocating revenue to deliverables as follows: (i) vendor-specific objective evidence of fair value (“VSOE”), (ii) third-party evidence of selling price (“TPE”) and (iii) best estimate of the selling price (“BESP”). VSOE generally exists only when the deliverable is sold separately and is the price actually charged for that deliverable. The process for determining BESP for deliverables without VSOE or TPE considers multiple factors including relative selling prices; competitive prices in the marketplace, and management judgment; however, these may vary depending upon the unique facts and circumstances related to each deliverable. The Company uses customer purchase orders that are subject to the Company’s terms and conditions or, in the case of an Original Equipment Manufacturer (“OEM”) are governed by distribution agreements. In accordance with the Company’s distribution agreements, the OEM does not have a right of return, and title and risk of loss passes to the OEM upon shipment. The Company generally ships Free On Board shipping point and uses shipping documents and third-party proof of delivery to verify delivery and transfer of title. In addition, the Company assesses whether collection is probable by considering a number of factors, including past transaction history with the customer and the creditworthiness of the customer, as obtained from third party credit references. If the terms of the sale include customer acceptance provisions and compliance with those provisions cannot be demonstrated, all revenue is deferred and not recognized until such acceptance occurs. The Company considers all relevant facts and circumstances in determining when to recognize revenue, including contractual obligations to the customer, the customer’s post-delivery acceptance provisions, if any, and the installation process. The Company has determined that iCAD’s digital and film based sales generally follow the guidance of FASB ASC Topic 605 “Revenue Recognition” (“ASC 605”) as the software has been considered essential to the functionality of the product per the guidance of ASU 2009-14. 2009-13. Revenue from certain CAD products is recognized in accordance with ASC 985-605. The Company recognizes post contract customer support revenue together with the initial licensing fee for certain MRI products in accordance with ASC 985-605-25-71. Sales of the Company’s Therapy segment products typically include a controller, accessories, source agreements and services. The Company allocates revenue to the deliverables in the arrangement based on the BESP in accordance with ASU 2009-13. The Company defers revenue from the sale of certain service contracts and recognizes the related revenue on a straight-line basis in accordance with ASC Topic 605-20, Cost of Revenue Cost of revenue consists of the costs of products purchased for resale, costs relating to service including personnel costs for physicists, management services and radiation therapists, costs of service contracts to maintain equipment after the warranty period, product installation, training, customer support, certain warranty repair costs, inbound freight and duty, cost of supplies, manufacturing, warehousing, material movement, inspection, scrap, rework, amortization, depreciation and in-house

Fair Value Measurements	Note 10 - Fair Value Measurements The Company follows the provisions of ASC Topic 820, “ Fair Value Measurement and Disclosures • 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. Our financial instruments include cash and cash equivalents, accounts receivable, accounts payable certain accrued liabilities and debt. The carrying amounts of our cash and cash equivalents (which are composed primarily of deposit and overnight sweep accounts), accounts receivable, accounts payable and certain accrued liabilities approximate fair value due to the short maturity of these instruments.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill	Note 12 - Goodwill In accordance with FASB ASC Topic 350-20, 350-20”), st 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 if such an assessment were to indicate that the fair value of a reporting unit was 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. As a result of the underperformance of the Therapy reporting unit as compared to expected future results, the Company determined there was a triggering event in the third quarter of 2017. As a result, the Company completed an interim impairment assessment. The interim test resulted in the fair value of the Therapy reporting unit being less than the carrying value of the reporting unit. The Company did not identify a triggering event within the Detection reporting unit and accordingly did not perform an interim test. The Company elected to early adopt ASU 2017-04, 2017-04”). 2017-04 The carrying values of the reporting units were determined based on an allocation of our assets and liabilities through specific allocation of certain assets and liabilities to the reporting units and an apportionment of the remaining net assets based on the relative size of the reporting units’ revenues and operating expenses compared to the Company as a whole. The determination of reporting units also requires management judgment. The Company determined 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 used internal forecasts to estimate future cash flows and includes an estimate of long-term future growth rates based on the most recent views of the long-term forecast for each segment. Accordingly, actual results can differ from those assumed in the forecasts. The discount rate of approximately 18% is derived from a capital asset pricing model and analyzing published rates for industries relevant to the 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 and in the 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 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 ours, as well as market data may not be available for divisions within larger conglomerates or non-public The Company corroborated 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 value. 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 weight the methodologies appropriately. As discussed in Note 3, in April 2015, the Company acquired VuComp’s M-Vu ® M-Vu In December 2016, the Company entered into an Asset Purchase Agreement with Invivo Corporation. The Company sold and conveyed to Buyer all right, title and interest to certain intellectual property relating to the VersaVue Software and the DynaCAD product and related assets. As a result of the Asset Purchase Agreement, the Company determined that the sale constituted the sale of a business and the Company allocated $394,000 of goodwill to assets held for sale as of December 31, 2016. The allocation was based on the fair value of the assets sold relative to the fair value of the Detection reporting unit as of the date of the Asset Purchase Agreement. The Company closed the transaction on January 30, 2017, and goodwill was a component of the net assets sold as of the closing date. A roll forward of goodwill activity by reportable segment is as follows (in thousands): Detection Therapy Total Balance at December 31, 2016 8,362 5,735 14,097 Impairment — (3,969 ) (3,969 ) Balance at September 30, 2017 $ 8,362 $ 1,766 $ 10,128 Accumulated Goodwill 699 6,270 54,906 Fair value allocation 7,663 13,446 — Accumulated impairment — (17,950 ) (44,778 ) Balance at September 30, 2017 $ 8,362 $ 1,766 $ 10,128

Long-lived Assets	Note 13 - Long-lived assets In accordance with FASB ASC Topic 360, “Property, Plant and Equipment” (“ASC 360”), 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 the carrying value of the asset group. ASC 360-10-35 360-10-35-21 • A significant decrease in the market price of a long-lived asset (asset group); • A significant adverse change in the extent or manner in which a long-lived asset (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 (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 (asset group); • A current period operating 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 (asset group). In accordance with ASC 360-10-35-17, The Company completed an interim goodwill impairment assessment for the Therapy reporting unit and noted that there was a goodwill impairment (see Note 13). As a result, the Company determined this was a triggering event for long-lived assets. Accordingly, the Company completed an analysis pursuant to ASC 360-10-35-17 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 the 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.

Revenue Recognition	Revenue Recognition The Company recognizes revenue primarily from the sale of products and from the sale of services and supplies. Revenue is recognized when delivery has occurred, persuasive evidence of an arrangement exists, fees are fixed or determinable and collectability of the related receivable is probable. For product revenue, delivery has occurred upon shipment provided title and risk of loss have passed to the customer. Services and supplies revenue are considered to be delivered as the services are performed or over the estimated life of the supply agreement. The Company recognizes revenue from the sale of its digital, film-based CAD and cancer therapy products and services in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Update No. 2009-13, 2009-13”) No. 2009-14, 2009-14”) 985-605, 985-605”). recognized in accordance with ASC 840 “Leases” (“ASC 840”). For multiple element arrangements, revenue is allocated to all deliverables based on their relative selling prices. In such circumstances, a hierarchy is used to determine the selling price to be used for allocating revenue to deliverables as follows: (i) vendor-specific objective evidence of fair value (“VSOE”), (ii) third-party evidence of selling price (“TPE”) and (iii) best estimate of the selling price (“BESP”). VSOE generally exists only when the deliverable is sold separately and is the price actually charged for that deliverable. The process for determining BESP for deliverables without VSOE or TPE considers multiple factors including relative selling prices; competitive prices in the marketplace, and management judgment; however, these may vary depending upon the unique facts and circumstances related to each deliverable. The Company uses customer purchase orders that are subject to the Company’s terms and conditions or, in the case of an Original Equipment Manufacturer (“OEM”) are governed by distribution agreements. In accordance with the Company’s distribution agreements, the OEM does not have a right of return, and title and risk of loss passes to the OEM upon shipment. The Company generally ships Free On Board shipping point and uses shipping documents and third-party proof of delivery to verify delivery and transfer of title. In addition, the Company assesses whether collection is probable by considering a number of factors, including past transaction history with the customer and the creditworthiness of the customer, as obtained from third party credit references. If the terms of the sale include customer acceptance provisions and compliance with those provisions cannot be demonstrated, all revenue is deferred and not recognized until such acceptance occurs. The Company considers all relevant facts and circumstances in determining when to recognize revenue, including contractual obligations to the customer, the customer’s post-delivery acceptance provisions, if any, and the installation process. The Company has determined that iCAD’s digital and film based sales generally follow the guidance of FASB ASC Topic 605 “Revenue Recognition” (“ASC 605”) as the software has been considered essential to the functionality of the product per the guidance of ASU 2009-14. 2009-13. Revenue from certain CAD products is recognized in accordance with ASC 985-605. The Company recognizes post contract customer support revenue together with the initial licensing fee for certain MRI products in accordance with ASC 985-605-25-71. Sales of the Company’s Therapy segment products typically include a controller, accessories, source agreements and services.
