System performance is substantially enhanced by using good attenuators in the system and employing a pulsing mode of operation. Spurious image elements, due to multiple reflections of the ultrasound in the acoustic cell and due to echoes from elements in the system which are not part of the object plane being imaged, can be eliminated in this fashion. In addition, depth discrimination can be substantially improved, in agreement with theory.
