Abstract
An ultrasonic cerebral infarction therapeutic apparatus that does not produce side effects of destruction of brain cells, occurrence of intracerebral hemorrhage, destruction of nerve cells, etc. by avoiding formation of a standing wave by interference between an irradiated beam of an ultrasonic wave irradiated to the inside of the cranium and its reflected beam. An ultrasonic probe cap is constructed by arranging a plurality of laminated small transducers each made up of a PVDF film, a PZT ceramic, or the like in a mosaic-like pattern or in other form on the inside of the cap and one or more transducers are selected and activated according to a thrombus position. As a high frequency for actuating a transducer, a continuous sinusoidal wave, a burst wave, or a pulse wave shall be used so that no standing wave may be produced inside the cranium.
