Abstract

A system is described that produces 30 ultrasonic images a second, which can be immediately stored on videodisc. Hundreds of these sequential cross-sectional images with very narrow intervals provide complete, three-dimensional information about an object. A videodisc system was chosen to record the ultrasonograms rather than a conventional data recording system or a videotape recorder because of the speed at which the videodisc system can record images and the ease with which it can play back data on demand from the computer. A method for determining the location, size and morphology of tumors, using transurethral ultrasonography and a DP system, is presented.
