ABSTRACT:
A pulse echo ultrasonic system is provided for medical diagnosis, and the like, which has particular application to echocardiography, and which includes a digital memory for presenting a rolling dynamic display in shades of gray on the screen of a cathode-ray tube scanned in accordance with present-day television standards, and which may be interfaced with present-day video tape recorders. The system of the invention involves a time extrapolating function which serves to expand the effective memory capacity when used in a selective mode applicable to echocardiography, and certain other bio-medical areas, such as scintillation camera displays, and other radiographic displays used in the area of medicine.
