摘要： An ultrasound medical treatment system capable of determining the hot spot at high spatial resolution, and preventing the displacement of the hot spot from the focal point. In the system, the imaging device for obtaining image data of a treatment portion containing a treatment target and an irradiation device for applying radiation onto the treatment target are controlled in such a manner that the imaging device is controlled to obtain hot spot detection image data after the irradiation device is controlled to apply radiation at a prescribed level, so that a hot spot indicating a change due to a temperature change caused by the radiation at the prescribed level can be detected from the hot spot detection image data. The irradiation device is then controlled to apply a treatment radiation at a treatment level higher than the prescribed level according to the detected hot spot.

摘要： An ultrasound medical treatment apparatus includes an ultrasound applicator for applying ultrasound irradiation to a treatment target. The treatment apparatus also includes an ultrasound imaging device that transmits ultrasound pulses to image the treatment target. The treatment apparatus is capable of reducing noises occurring at an ultrasound imaging device due to the ultrasound irradiation generated by the ultrasound application during ultrasound medical treatment. The noises may be reduced by increasing a transmission power of the ultrasound pulses. Alternatively, the noises may be reduced by subtracting pre-recorded noise components from the ultrasound pulses received by the ultrasound imaging device, where the pre-recorded noise components are characteristic of noise occurring at the ultrasound imaging device due to the ultrasound irradiation generated by the ultrasound applicator.

摘要： An ultrasonic diagnosis apparatus for raising tissue temperature for hypothermic treatments, including an ultrasonic source for generating an ultrasonic treatment wave and a driving means for driving the ultrasonic source such that a frequency of the ultrasonic treatment wave generated by the ultrasonic source changes with time. The frequency of the ultrasonic treatment wave is changed along the time axis. By this change in frequency, some bubbles formed by cavitation as a result of the ultrasonic treatment wave are divided, and some bubbles are collapsed and therefore eliminated. Side effect cavitation and spread of a thermal degeneration area is suppressed, and thermal degeneration can be accurately induced in a desired area, thereby realizing a reliable, safe ultrasonic thermotherapy. Since cavitation is positively suppressed, the total treatment period can be shortened because cavitation would otherwise interfere with and slow down the thermal degeneration process. Therefore, treatment throughput can be improved as compared with a case in which cavitation is left to naturally break and disappear.

摘要： 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.
