Abstract
This paper describes a supersonic-imulse-echo method employing double-focusing for selective depiction of certain internal body layers. By employing the impulse echo principle, a point supersonic source is focused on the object element to be examined by means of a sound-optical system; the echo reflected by the object element is focused by the same soundoptics on the identical effectively point-shaped sound receiver and is transformed into a voltage impulse that serves for the production of an image. First results of experiments confirm an essential improvement in SNR as was expected.Keywords
