ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

     The Agreement and Plan of Merger described in Item 6 of this Statement was
entered into by GE and Imatron and was closed on December 19, 2001. The
securities were acquired in connection with the closing of the Merger Agreement.
Upon the closing of the Merger, each outstanding share of Imatron common stock
was converted into the right to receive 0.051 shares of GE common stock, par
value $0.06 per share, plus cash in lieu of fractional shares.

ITEM 4. PURPOSE OF TRANSACTION

     GE entered into the Merger Agreement described in Item 6 in order to
acquire all of the outstanding Common Stock of Imatron. GE intends to operate
Imatron as a wholly owned subsidiary. Following the Merger, GE, as the sole
shareholder of Imatron, adopted new articles of incorporation and bylaws,
changed the number of directors, elected new directors, and reduced the
capitalization of Imatron. Imatron's common stock was, upon the consummation of
the Merger, eligible for termination of registration and was delisted from the
Nasdaq System.

ITEM 5. INTEREST IN SECURITIES OF ISSUER

     (a) - (c) By reason of the Merger, GE owns 100% of the outstanding common
stock of Imatron. GE has the sole power to vote all of the shares of Imatron
stock. The Merger was effected on December 19, 2001, following a meeting of the
stockholders of Imatron. The price per share of the transaction is described
under Item 3.

     Except as described in this Schedule 13D, neither GE nor, to the best
knowledge of GE, any of the persons listed in Item 2 above beneficially owns any
shares of Imatron common stock. Except as described in this Schedule 13D,
neither GE nor, to the best of its knowledge, any of the persons listed in Item
2 above has effected any transactions in Imatron common stock since the last
Schedule 13D was filed by the Reporting Person on September 26, 2001.

     (d)  Not applicable.

     (e)  Not applicable.
