ABSTRACT:
An ultrasonic pulse is directed into a body and electrical representations of pulse reflections from body interfaces along its path are generated. The ultrasonic signal path is scanned through a volume of the body and position signals indicative of the instantaneous path disposition are generated. The reflection signals are selectively gated in accordance with a predetermined function of the path disposition to provide a display selectively representing desired interfaces situated within a selected contoured portion of the volume. By varying the predetermined function, a specific desired interface surface may be displayed. Provisions for developing a three dimensional display of the selected surface are described.
