ABSTRACT:
An ultrasound generator for acoustic irradiation of pathological changes of a human body comprises a planarly fashioned piezo-electric transducer which is acoustically coupled to an acoustical lens on one surface by a soft metal layer and is acoustically coupled on the opposite surface by a second soft metal layer to a dampening member. The soft metal layers act as both acoustically coupling layers and as electrodes for the piezo-electric transducer. The piezo-electric transducer can be formed of either a plurality of layers which are spaced apart by soft metal layers acting as electrodes, a single piezo-electric plate, or a plurality of plates arranged side by side in the same plane.
