Abstract
An ultrasonic bidirectional transducer array, and an imaging system including said array, wherein the array comprises a plurality of transducer elements each having a major face capable of bidirectionally transmitting and receiving ultrasonic energy and an opposite face. The transducer elements have their major bidirectional faces arrayed in a predetermined surface. Means is carried by the opposite face of each element for bidirectionally providing and receiving electrical energy across each transducer element. In the imaging system the array may be selectively scanned to provide successive displays of moving objects at a rate which gives the impression of continuous motion to a human observer.
