摘要： 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.

摘要： This invention relates to an apparatus for disintegrating calculus having a main ultrasonic transducer for emitting a high power ultrasonic shock wave to disintegrate a kidney stone in a patient, and for emitting a weak ultrasonic shock wave, before emitting the high power ultrasonic shock wave. A sound receiver receives sounds generated by the patient's body in response to the weak ultrasonic shock wave, and converts the sounds into electrical signals. A kidney stone confirming circuit receives electrical signals from the sound receiver and determines whether the kidney stone is positioned at the focal point of the main transducer. The apparatus prevents the emission of the high power ultrasonic shock wave when the position of the kidney stone is not coincident with the focal point of the main transducer in order to prevent any harm to the patient's normal tissue.
