ABSTRACT:
An ultrasonic therapy apparatus includes a treating ultrasonic transducer, a driving section, an imaging ultrasonic transducer, a tomographic image forming section, and a position control section. The treating transducer is driven by the driving section, and generates a treating ultrasonic wave focused at a predetermined focal point in a body of an object to be examined. The imaging ultrasonic transducer is movably arranged, and transmits and receives an imaging ultrasonic wave for obtaining a tomographic image of the object to be examined. The tomographic image forming section drives the imaging transducer to transmit the imaging ultrasonic wave, and forms the tomographic image of the object to be examined based on an ultrasonic echo signal received by the imaging transducer. The position control section controls the position of the imaging ultrasonic transducer within a predetermined range along a line connecting a central point of the treating ultrasonic transducer and the focal point of the treating ultrasonic wave.
