PROBLEM TO BE SOLVED: To provide an ultrasound diagnostic apparatus allowing an ultrasound probe to operate continuously for a long time and, when being diagnostically required, providing high-definition ultrasound images.SOLUTION: The ultrasound diagnostic apparatus is configured to select either of a first mode in which ultrasound waves are transmitted/received by an oscillator array of the ultrasound probe 1, while a power is supplied thereto by a wireless power supply section 28, and a second mode in which the power supply is stopped by the wireless power supply section 28 and ultrasound waves are transmitted/received by the oscillator array of the ultrasound probe 1, and controls, based on the mode, the power supply by the wireless power supply section 28 and the transmission/reception of the ultrasound waves by the oscillator array of the ultrasound probe 1.COPYRIGHT: (C)2012,JPO&INPIT【課題】超音波プローブの長時間の連続稼働を可能にするとともに、診断上で必要な場合、高画質の超音波画像を得ることもできる超音波診断装置を提供する。【解決手段】無線給電部28により給電を行いながら超音波プローブ1の振動子アレイによる超音波の送受信を行う第1のモード及び無線給電部28により給電を停止させて超音波プローブ1の振動子アレイによる超音波の送受信を行う第2のモードのいずれかが選択され、そのモードに基づいて無線給電部28による給電および超音波プローブ1の振動子アレイによる超音波の送受信を制御する。【選択図】図1
