Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited financial statements of Stereotaxis, Inc. (the "Company") have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all the disclosures required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, they include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods presented. Operating results for the nine month period ended September 30, 2011 are not necessarily indicative of the results that may be expected for the year ended December 31, 2011 or for future operating periods. These interim financial statements and the related notes should be read in conjunction with the annual financial statements and notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2010 as filed with the Securities and Exchange Commission (SEC) on March 11, 2011. Revenue and Costs of Revenue For arrangements with multiple deliverables, the Company allocates the total revenue to each deliverable based on the provisions of general accounting principles for revenue recognition and multiple-deliverable revenue arrangements and recognizes revenue for each separate element as the criteria for revenue recognition are met. Each element is assigned an estimated selling price using vendor-specific objective evidence, third party evidence, or management's estimate. Under our revenue recognition policy, a portion of revenue for NIOBE, ODYSSEY VISION, and ODYSSEY CINEMA systems is recognized upon delivery, provided that title has passed, there are no uncertainties regarding acceptance, persuasive evidence of an arrangement exists, the sales price is fixed and determinable, and collection of the related receivable is reasonably assured. Revenue is recognized for other types of ODYSSEY systems upon completion of installation, since there are no qualified third party installers. We may deliver systems to a non-hospital site at the customer's request. We evaluate whether delivery has occurred considering general accounting principles for revenue recognition with respect to "bill and hold" transactions. Amounts collected prior to satisfying the above revenue recognition criteria are reflected as deferred revenue. Revenue from services and license fees, whether sold individually or as a separate unit of accounting in a multiple-deliverable arrangement, is deferred and amortized over the service or license fee period, which is typically one year. Revenue from services is derived primarily from the sale of annual product maintenance plans. We recognize revenue from disposable device sales or accessories upon shipment and establish an appropriate reserve for returns. The return reserve, which is applicable only to disposable devices, is estimated based on historical experience which is periodically reviewed and updated as necessary. In the past, changes in estimate have had only a de minimus effect on revenue recognized in the period. We believe that the estimate is not likely to change significantly in the future. Costs of systems revenue include direct product costs, installation labor and other costs, estimated warranty costs, and initial training and product maintenance costs. These costs are recorded at the time of sale. Costs of disposable revenue include direct product costs and estimated warranty costs and are recorded at the time of sale. Cost of revenue from services and license fees are recorded when incurred. Net Loss per Common Share Basic and diluted net loss per common share is computed by dividing the net loss for the period by the weighted average number of common shares outstanding during the period. The largest adjustment between the shares outstanding at September 30, 2011 and the weighted average shares used for calculating basic earnings per share for the quarter ended September 30, 2011 is the deduction of unvested restricted shares, which amounted to 531,202 at September 30, 2011. In addition, the Company did not include any portion of unearned restricted shares, outstanding options, stock appreciation rights or warrants in the calculation of diluted loss per common share because all such securities are anti-dilutive for all periods presented. The application of the two-class method of computing earnings per share under general accounting principles for participating securities is not applicable because the Company's unearned restricted shares do not contractually participate in its losses. As of September 30, 2011, the Company had 5,711,316 shares of common stock issuable upon the exercise of outstanding options and stock appreciation rights at a weighted average exercise price of $5.00 per share and 10,381,613 shares of common stock issuable upon the exercise of outstanding warrants at a weighted average exercise price of $4.20 per share. The Company had a weighted average of 517,537 and 455,001 unearned restricted shares outstanding for the three and nine months ended September 30, 2011, respectively. Fair Value Measurements The Company measures certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents and warrants. General accounting principles for fair value measurement established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities ("Level 1") and the lowest priority to unobservable inputs ("Level 3"). The Company's financial assets consist of cash equivalents invested in money market funds in the amount of $43,471 and $12,238,932 at September 30, 2011 and December 31, 2010, respectively. These assets are classified as Level 1 as described above and total interest income recorded for these investments was approximately $30 and $1,400 during the three and nine months ended September 30, 2011. There were no transfers in or out of Level 1 during the nine months ended September 30, 2011. The Company's financial liabilities consist of warrants in the amount of $289,976 at September 30, 2011. These liabilities are classified as Level 3 as described above and are measured using the Black-Scholes valuation model. The mark-to-market adjustment recorded in other income (expense) for these warrants was $2,611,067 and $3,251,822 during the three and nine months ended September 30, 2011. There were no purchases, sales, issuances, transfers, or settlements of Level 3 financial instruments during the nine months ended September 30, 2011. These warrants were transferred into Level 3 on January 1, 2009 based on the adoption of general accounting principles for determining whether an instrument (or embedded feature) is indexed to an entity's own stock. See Note 11 for additional details. Fair Value – Other Financial Instruments The following methods and assumptions were used by the Company in estimating its fair value disclosures for other financial instruments as of September 30, 2011 and December 31, 2010. Cash and cash equivalents, accounts receivable, accounts payable and accrued expenses have carrying values which approximate fair value due to the short maturity or the financial nature of these instruments. Long and short-term debt fair value estimates are based on estimated borrowing rates to discount the cash flows to their present value. See Note 9 for disclosure of the fair value of debt. Share-Based Compensation The Company accounts for its grants of stock options, stock appreciation rights and restricted shares and for its employee stock purchase plan in accordance with the provisions of general accounting principles for share-based payments. These accounting principles require the determination of the fair value of the share-based compensation at the grant date and the recognition of the related expense over the period in which the share-based compensation vests. The Company utilizes the Black-Scholes valuation model to determine the fair value of stock options and stock appreciation rights at the date of grant. The resulting compensation expense is recognized over the requisite service period, which is generally four years. Compensation expense is recognized only for those awards expected to vest, with forfeitures estimated based on the Company's historical experience and future expectations. Restricted shares granted to employees are valued at the fair market value at the date of grant. The Company amortizes the amount to expense over the service period on a straight-line basis. If the shares are subject to performance objectives, the resulting compensation expense is amortized over the anticipated vesting period and is subject to adjustment based on the actual achievement of objectives. Recently Issued Accounting Pronouncements In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2011-04, "Fair Value Measurement: Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS". The Update amends the guidance on fair value measurements to develop common requirements for measuring fair value and for disclosing information about fair value measurements in accordance with US GAAP and International Financial Reporting Standards ("IFRS"). The Update does not require additional fair value measurements and is not intended to establish valuation standards or affect valuation practices outside of financial reporting. This guidance is effective during interim and annual periods beginning after December 15, 2011. In June 2011, the FASB issued new accounting guidance related to the presentation of comprehensive income that increases comparability between U.S. GAAP and International Financial Reporting Standard. This guidance eliminates the current option to report other comprehensive income (OCI) and its components in the statement of changes in stockholders' equity. This guidance is effective for the Company's interim and annual periods beginning January 1, 2012. As the Company has no items of other comprehensive income, the Company is not required to report comprehensive income or other comprehensive income.

Accordingly, they do not include all the disclosures required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, they include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods presented. Operating results for the nine month period ended September 30, 2011 are not necessarily indicative of the results that may be expected for the year ended December 31, 2011 or for future operating periods.

These interim financial statements and the related notes should be read in conjunction with the annual financial statements and notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2010 as filed with the Securities and Exchange Commission (SEC) on March 11, 2011.

For arrangements with multiple deliverables, the Company allocates the total revenue to each deliverable based on the provisions of general accounting principles for revenue recognition and multiple-deliverable revenue arrangements and recognizes revenue for each separate element as the criteria for revenue recognition are met. Each element is assigned an estimated selling price using vendor-specific objective evidence, third party evidence, or management's estimate.

Under our revenue recognition policy, a portion of revenue for NIOBE, ODYSSEY VISION, and ODYSSEY CINEMA systems is recognized upon delivery, provided that title has passed, there are no uncertainties regarding acceptance, persuasive evidence of an arrangement exists, the sales price is fixed and determinable, and collection of the related receivable is reasonably assured.

We may deliver systems to a non-hospital site at the customer's request. We evaluate whether delivery has occurred considering general accounting principles for revenue recognition with respect to "bill and hold" transactions. Amounts collected prior to satisfying the above revenue recognition criteria are reflected as deferred revenue.

Revenue from services and license fees, whether sold individually or as a separate unit of accounting in a multiple-deliverable arrangement, is deferred and amortized over the service or license fee period, which is typically one year. Revenue from services is derived primarily from the sale of annual product maintenance plans. We recognize revenue from disposable device sales or accessories upon shipment and establish an appropriate reserve for returns.

Costs of systems revenue include direct product costs, installation labor and other costs, estimated warranty costs, and initial training and product maintenance costs. These costs are recorded at the time of sale. Costs of disposable revenue include direct product costs and estimated warranty costs and are recorded at the time of sale. Cost of revenue from services and license fees are recorded when incurred.

Net Loss per Common Share

Basic and diluted net loss per common share is computed by dividing the net loss for the period by the weighted average number of common shares outstanding during the period. The largest adjustment between the shares outstanding at September 30, 2011 and the weighted average shares used for calculating basic earnings per share for the quarter ended September 30, 2011 is the deduction of unvested restricted shares, which amounted to 531,202 at September 30, 2011.

In addition, the Company did not include any portion of unearned restricted shares, outstanding options, stock appreciation rights or warrants in the calculation of diluted loss per common share because all such securities are anti-dilutive for all periods presented. The application of the two-class method of computing earnings per share under general accounting principles for participating securities is not applicable because the Company's unearned restricted shares do not contractually participate in its losses.

As of September 30, 2011, the Company had 5,711,316 shares of common stock issuable upon the exercise of outstanding options and stock appreciation rights at a weighted average exercise price of $5.00 per share and 10,381,613 shares of common stock issuable upon the exercise of outstanding warrants at a weighted average exercise price of $4.20 per share. The Company had a weighted average of 517,537 and 455,001 unearned restricted shares outstanding for the three and nine months ended September 30, 2011, respectively.

The Company measures certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents and warrants. General accounting principles for fair value measurement established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities ("Level 1") and the lowest priority to unobservable inputs ("Level 3").

The Company's financial assets consist of cash equivalents invested in money market funds in the amount of $43,471 and $12,238,932 at September 30, 2011 and December 31, 2010, respectively. These assets are classified as Level 1 as described above and total interest income recorded for these investments was approximately $30 and $1,400 during the three and nine months ended September 30, 2011. There were no transfers in or out of Level 1 during the nine months ended September 30, 2011.

The Company's financial liabilities consist of warrants in the amount of $289,976 at September 30, 2011. These liabilities are classified as Level 3 as described above and are measured using the Black-Scholes valuation model. The mark-to-market adjustment recorded in other income (expense) for these warrants was $2,611,067 and $3,251,822 during the three and nine months ended September 30, 2011. There were no purchases, sales, issuances, transfers, or settlements of Level 3 financial instruments during the nine months ended September 30, 2011. These warrants were transferred into Level 3 on January 1, 2009 based on the adoption of general accounting principles for determining whether an instrument (or embedded feature) is indexed to an entity's own stock. See Note 11 for additional details.

Fair Value – Other Financial Instruments

The following methods and assumptions were used by the Company in estimating its fair value disclosures for other financial instruments as of September 30, 2011 and December 31, 2010.

Cash and cash equivalents, accounts receivable, accounts payable and accrued expenses have carrying values which approximate fair value due to the short maturity or the financial nature of these instruments.

Long and short-term debt fair value estimates are based on estimated borrowing rates to discount the cash flows to their present value. See Note 9 for disclosure of the fair value of debt.

Share-Based Compensation

The Company accounts for its grants of stock options, stock appreciation rights and restricted shares and for its employee stock purchase plan in accordance with the provisions of general accounting principles for share-based payments. These accounting principles require the determination of the fair value of the share-based compensation at the grant date and the recognition of the related expense over the period in which the share-based compensation vests.

The Company utilizes the Black-Scholes valuation model to determine the fair value of stock options and stock appreciation rights at the date of grant. The resulting compensation expense is recognized over the requisite service period, which is generally four years. Compensation expense is recognized only for those awards expected to vest, with forfeitures estimated based on the Company's historical experience and future expectations. Restricted shares granted to employees are valued at the fair market value at the date of grant. The Company amortizes the amount to expense over the service period on a straight-line basis. If the shares are subject to performance objectives, the resulting compensation expense is amortized over the anticipated vesting period and is subject to adjustment based on the actual achievement of objectives.

Recently Issued Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2011-04, "Fair Value Measurement: Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRS". The Update amends the guidance on fair value measurements to develop common requirements for measuring fair value and for disclosing information about fair value measurements in accordance with US GAAP and International Financial Reporting Standards ("IFRS"). The Update does not require additional fair value measurements and is not intended to establish valuation standards or affect valuation practices outside of financial reporting. This guidance is effective during interim and annual periods beginning after December 15, 2011.

In June 2011, the FASB issued new accounting guidance related to the presentation of comprehensive income that increases comparability between U.S. GAAP and International Financial Reporting Standard. This guidance eliminates the current option to report other comprehensive income (OCI) and its components in the statement of changes in stockholders' equity. This guidance is effective for the Company's interim and annual periods beginning January 1, 2012. As the Company has no items of other comprehensive income, the Company is not required to report comprehensive income or other comprehensive income.
