Paper Abstract

This paper describes the electronic requirements and solutions to those requirements to support a very high resolution interactive medical image display system. The paper is a companion to a paper to be presented at this conference describing the design of the special multibeam CRT which is a key element in the system. The electronic support package for the multibeam tube must be capable of supplying a video bandwidth of more than 400 Mhz. An image memory supplying the 400 MHz. pixel stream must store at least 16 images of 4 million, 8 bit pixels, each. Each image must be refreshed 60 times a second thus requiring effective horizontal sweep rates of 240 KHz. The design which meets these requirements has been completed and will be described in this paper. These requirements were achieved by using an inten sively parallel design in conjuction with the multibeam CRT, described elsewhere. Memory and logical components were combined in such a way as to provide electronic signal storage and transmission speeds far exceeding the current state of the art. In this development, a valuable contribution to medical electronics has been made which makes possible the interactive display, manipulation and analysis, in real time, of medical images with resolution of 2048 x 2048 or 4096 x 4096 pixels. This resolution equals the quality expected from photographic films.
