Investments, All Other Investments [Abstract]
Investment in Privately Held Company	7. Investment in Privately Held Company The Company had an original investment in a privately held Israeli-based company in the amount of $100,000. The privately held company offers surgeons and radiologists the ability to detect cancer in real time. Due to the fact that the privately held company has experienced delays in executing its business plan, the Company determined to write down the value of its investment (included in other assets in the accompanying consolidated balance sheets) to $65,000 at December 31, 2013 and to $50,000 at December 31, 2015. The Company further wrote down the value of its investment to $35,000 at December 31, 2016 and to $15,000 at December 31, 2017, resulting in a charge to the statement of operations of $15,000 and $20,000, respectively, for the years ended December 31, 2016 and 2017.

The entire disclosure for investments accounted for under the cost-method. The carrying amount of such investments may be adjusted, for example, distributions in excess of cost (return of capital) or for other-than-temporary impairments. The cost method and lower-of-cost or market, an adaptation of the cost method, is generally followed for most investments in noncontrolled corporations, in some corporate joint ventures, and to a lesser extent in unconsolidated subsidiaries in which the entity does not have the ability to exercise significant influence.
