Abstract
An ultrasonic therapeutical apparatus observes the interior of a living body utilizing an ultrasonic wave, allows a location signal to be generated on the basis of an output from the observation system, and controls a focus shifting system in accordance with the location signal. Subsequently, a shock wave generating system is driven to generate an ultrasonic shock wave, which is directed to a focal point, thereby crushing a calculus.
