摘要： The invention relates to an apparatus and method for disintegrating calculus having a main ultrasonic transducer for emitting a high power ultrasonic shockwave to disintegrate a kidney stone of a patient. The apparatus further includes a means for emitting a weak ultrasonic shockwave before emitting the high power ultrasonic shockwave, kidney stone confirming circuit for confirming the position of the kidney stone and a microphone for receiving sounds from the kidney stone. The kidney stone confirming circuit receives electric signals from the microphone and determines whether the position of the kidney stone is at the focal point of the main transducer. The apparatus is capable to prohibit the emittion of the high power ultrasonic shockwave when the position of the kidney stone is not coincident with the focal point of the main transducer in order to prevent harmful effects to normal tissues of the patient.

摘要： An ultrasonic wave medical treatment in which the position of the focal point of the ultrasonic waves, the temperature in a vicinity of the object to be treated, and the effect of the treatment can be determined easily and accurately. The three-dimensional image information of the object (7) to be treated obtained by a computed tomography device (9,10,11,14,15) is utilized in locating the focal point (6). In case of using a nuclear magnetic resonance imaging device as the computed tomography device, the T2 weighted image and the chemical shift data can be used in checking the effect of the treatment and the temperature in a vicinity of the object (7) The endocavitary probe equipped with temperature and intensity sensors may also be used. The ultrasound tomographic images obtained by the ultrasound tomographic imaging device may also be used in conjunction with the three-dimensional image information. Sequential shifting of the focal point (6) of the ultrasonic waves may be employed to reduce adverse influence due to the cavitation.
