ABSTRACT:
An ultrasonic sound beam is caused to penetrate an object to be inspected and is moved in a scanning plane of the object transversely to the axis of the beam. A B-scan display of the object is displayed on a display screen in response to echo pulses produced by the object under the action of the sound beam moving in the plane. An adjustable trace is defined on the display screen at a location which corresponds to a predetermined position of the sound beam during the movement thereof in the plane. A display other than the B-scan display is derived from echo pulses produced by said object under the action of said sound beam when the same is in said predetermined position.
