Abstract
In the illustrated embodiment, an electronic receiving gate is inserted between the image display device and the ultrasonic echo receiver so as to allow only echo impulses from a selected depth of field to pass through to the image display device. The depth selection is effected without any change in the line and image scanning rates by shifting the receiving gate between its transmitting and blocking states in the rhythm of the line sweep pulses and by adjusting the moment of emission of the ultrasonic pulses within the blocking phase of the receiving gate.
