Abstract
An ultrasound therapy apparatus delivers focused ultrasound for therapeutical purposes which can be correctly targeted to a target region, and also, a positional shift from the target region under irradiation of ultrasound can be effectively avoided. An ultrasound transducer is inside an applicator with an imaging ultrasonic probe. Another ultrasound transducer monitors a position of a target and a positional shift is inside a catheter which is inserted into a urethral tube. An imaging system drives the ultrasound probe to display an ultrasound tomographic image of a region in the vicinity of a target region. The ultrasound transducer is driven in a pulse-shaped mode at the same frequency as the imaging ultrasound and also at such timing when the imaging ultrasound is reached. As a result, a point-shaped sound source image is superimposed and displayed on an ultrasound tomographic image.
