PROBLEM TO BE SOLVED: To perform an ultrasonic treatment while suppressing an adverse effect on a normal tissue, etc.SOLUTION: An ultrasonic treatment apparatus includes an ultrasonic treatment probe 37 for irradiating a treatment target part of a living body with a treatment ultrasonic wave, and a treatment probe control part 49 for controlling the ultrasonic treatment probe 37. The ultrasonic treatment probe 37 includes a hemispherical concave surface where a plurality of treatment vibrators 39 are disposed for converting an electric signal to an ultrasonic wave and emitting the ultrasonic wave. On the basis of determination information that determines whether or not there exists an area where irradiation of a predetermined treatment ultrasonic wave is inhibited in a treatment ultrasonic wave irradiation route 404 of each treatment vibrator 39, the treatment probe control part 49 selectively turns off the electric signal supplied to the treatment vibrator for which there exists an area where irradiation of a predetermined treatment ultrasonic wave is inhibited.COPYRIGHT: (C)2015,JPO&INPIT【課題】正常組織等への悪影響を抑制して超音波治療を行う。【解決手段】生体の治療対象部位に治療超音波を照射する超音波治療プローブ37と、超音波治療プローブ37を制御する治療プローブ制御部49とを備え、超音波治療プローブ37は、電気信号を超音波に変換して射出する複数の治療振動子39が配設された半球状の凹面を備え、治療プローブ制御部49は、それぞれの治療振動子39の治療超音波照射経路404にあらかじめ定めた治療超音波の照射不可領域が存在するか否かを判別した判別情報に基づいて、照射不可領域が存在する治療振動子に供給される電気信号を選択的にオフすることを特徴とする。【選択図】 図2
