Provided on the side of a distal end of an insertion part are an observation ultrasonic transducer for acquiring an ultrasonic image and a therapeutic ultrasonic transducer for outputting a therapeutic ultrasonic wave so as to be focused. Positioning or the like between the observation ultrasonic transducer and the therapeutic ultrasonic transducer is so conducted that a focusing point at which the therapeutic ultrasonic wave is focused is locked to a predetermined position within a scanning range of the observation ultrasonic wave. If the position of the focusing point is locked whereby a lesion part to be treated is set to a predetermined position on an ultrasonic image, it is necessarily possible to conduct the position setting to the focusing point. It is also made possible to confirm the position of the lesion part and to acoustically observe a state of the lesion part during irradiation of the therapeutic ultrasonic wave.

Title
Ultrasonic diagnosis and therapy system in which focusing point of therapeutic ultrasonic wave is locked at predetermined position within observation ultrasonic scanning range
