Interactive Raster Graphics for CT Scans

Abstract

Computerised Tomography (CT) scanning is now a very important radiological technique, with a large number of machines distributed all over the world in a comparatively short space of time. All machines have their own viewing systems for examining the scan pictures. Some of these are incorporated in the scanner electronics and computer system. Others have a separate independent viewing system (produced by the same manufacturer) to which the scan pictures are taken, usually by floppy disk or magnetic tape, both of which will have been generated on the main scanner system. Some manufacturers have provided an integrated scanning and treatment planning arrangement. But since we already had a fully developed treatment planning computer ourselves, we wished to develop our own way of incorporating CT scans, and displaying them with treatment plans superimposed.
