Title: Signal converter for ultrasonic body scanners - produces TV display from stored scan data in random access memory uses clock pulses generator (NL91176)
Inventor: GRANDCHAMP PIERRE ANDRE
IPC: A61B8/00
Filed: 1976-05-05
Abstract: The signal converter for ultrasonic medical diagnosis consists of an ultrasonic scanning apparatus with receiver connected to an analog-digital converter. Additional signals related to the geometrical position of each set of echoes are sent to a control unit. A clock-pulse generator in the control unit running at 2 MHz transfers picture information into a random-access memory and from this memory into an intermediate store. Read or write address information is also transmitted. Another series of pulses causes the contents of the intermediate shift-register to be read out. The information corresponds to the number of picture elements in each line of the picture scan. This is fed to a television tube via a digital-analog converter. The television display is synchronised with the pulse control unit.
