        This Amendment No. 1 to the statement on Schedule 13D originally filed by Imatron Inc. on February 1, 1999, is filed by General Electric Company ("GE") and relates to the Common Stock, par value $0.01 per share (the "Common Stock"), of Positron Corporation, a Texas corporation (the "Issuer" or "Positron"). Imatron Inc. was merged with and into General Electric Corporation on June 26, 2003. That Schedule 13D is hereby amended as set forth below.

Item 2. Identity and Background

        The Reporting Person is General Electric Company, a New York corporation ("GE"). Because GE and Imatron Inc. were merged on June 26, 2003, GE is filing this amendment to the 13D originally filled by Imatron Inc. GE is one of the largest and most diversified industrial corporations in the world. GE has engaged in developing, manufacturing and marketing a wide variety of products for the generation, transmission, distribution, control and utilization of electricity since its incorporation in 1892. Over the years, GE has developed or acquired new technologies and services that have broadened considerably the scope of its activities.

        GE's products include major appliances; lighting products; industrial automation products; medical diagnostic imaging equipment; motors; electrical distribution and control equipment; locomotives; power generation and delivery products; nuclear power support services and fuel assemblies; commercial and military aircraft jet engines; and engineered materials, such as plastics, silicones and superabrasive industrial diamonds.

        GE's services include product services; electrical product supply houses; electrical apparatus installation, engineering, repair and rebuilding services; and computer-related information services. Through its affiliate, the National Broadcasting Company, Inc., GE delivers network television services, operates television stations, and provides cable programming and distribution services. Through another affiliate, General Electric Capital Services, Inc., GE offers a broad array of financial and other services including consumer financing, commercial and industrial financing, real estate financing, asset management and leasing, mortgage services, consumer savings and insurance services, specialty insurance and reinsurance, and satellite communications.

        GE operates in more than 100 countries around the world, including 280 manufacturing plants in 26 different nations. GE's principal executive offices are located at 3135 Easton Turnpike, Fairfield, CT 06431 (telephone (203) 373-2211).

        The names, business address and principal occupations of each of Reporting Person's executive officers and directors are set forth in Exhibit A attached hereto, which is incorporated herein by this reference. All such persons are citizens of the United States unless otherwise noted in Exhibit A.

        During the last five years, none of the persons named in this Item 2 has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

        GE has not and, to the best of GE's knowledge, none of the directors and executive officers of GE has been, during the last five years, a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree, or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 4. Purpose of Transaction

        On June 29, 2003, GE and Positron entered into a transaction pursuant to which GE surrendered for cancellation Positron's $2,000,000 note and accrued interest, 9,000,000 shares of Positron's common stock and a warrant exercisable for 6,000,000 shares of Positron's common stock in exchange for Positron selling to GE its cardiac PET software. In connection with the transaction, GE granted Positron a worldwide, perpetual, non-exclusive, royalty-free license to use the transferred cardiac PET


software, and GE and Positron entered into a services agreement whereby GE will pay Positron to provide support to transition the software to GE.

Item 5. Interest in Securities of the Issuer

        General Electric no longer owns any equity securities of Positron. As a result, General Electric is no longer a 5% beneficial owner of securities of Positron.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

        As noted above in Item 4, GE and Positron entered into a Technology Purchase Agreement pursuant to which GE surrendered for cancellation Positron's $2,000,000 note and accrued interest, 9,000,000 shares of Positron's common stock and a warrant exercisable for 6,000,000 shares of Positron's common stock in exchange for Positron selling to GE its cardiac PET software. The Technology Purchase Agreement is attached hereto as Exhibit 99.1 and is incorporated herein by reference.


Item 7. Material to Be Filed as Exhibits


        After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
