ABSTRACT:
An ultrasonic wave medical treatment apparatus capable of preventing the displacement of the focal point of the ultrasonic waves from the treatment target portion within the patient, eliminating a need for re-positioning of the ultrasonic wave applicator with respect to the patient, and taking MR images to be utilized during the treatment at a high resolution. In this apparatus, the ultrasonic wave applicator can be integrally incorporated within a treatment table for carrying the patient into the MRI gantry for taking the MR images. The surface coil for taking the MR images can be provided on a surface film of a water bag in the ultrasonic wave applicator, or on a body cavity probe on which the ultrasonic transducer is also provided. The mixing rate of the coupling fluid can be adjusted, and the impedance matching between the ultrasonic transducer and the driving circuit can be maintained by minimizing the reflected electric power from the ultrasonic transducer.
