ABSTRACT:
A shock wave treatment apparatus has a shock wave applicator including a shock wave transducer for forming a focusing region of a shock wave for destroying an object to be destroyed in an object to be examined, and an ultrasonic transducer for transmitting/receiving an ultrasonic wave and acquiring ultrasonic tomographic image information. The shock wave applicator is aligned with the object to be destroyed, such that an overlap degree between a focusing region of the shock wave and the object to be destroyed is discriminated by an overlap degree discrimination circuit. When the calculation result of the overlap is smaller than a predetermined value, control is performed not to generate a shock wave. On the other hand, the shock wave application is mechanically aligned with the object, such that a support device supporting the applicator is operated so that a focal point position of the shock wave in the object to be examined can be moved to coincide with the object to be destroyed.
