Apparatus for ultrasonic wave medical treatment using computed tomography

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.
