PROBLEM TO BE SOLVED: To enable an observation of the state of the tissue for a prescribed period in ultrasonic diagnostic equipment.SOLUTION: Ultrasonic diagnostic equipment includes: an ultrasonic wave transmitting/receiving part and a control part. The ultrasonic wave transmitting/receiving part transmits and receives ultrasonic waves in a state of being inserted into a specimen so as to obtain biological information of the prescribed portion of the specimen. The control part intermittently makes the ultrasonic wave transmitting/receiving part transmit ultrasonic waves, based on a trigger signal set according to a cyclically operating prescribed portion, or a trigger signal acquired according to the state, in a plurality of cycles based on the cycle of the operation.COPYRIGHT: (C)2014,JPO&INPIT【課題】超音波診断装置において、所定期間、体内組織の状態を観察することを可能とする。【解決手段】超音波診断装置は、超音波送受信部と、制御部とを有する。超音波送受信部は、被検体内に挿入された状態で超音波を送受信することにより被検体の所定部位の生体情報を得る。制御部は、周期的に動作する所定部位の状態に応じて設定されたトリガ信号、または当該状態に応じて求められたトリガ信号に基づき、間欠的に、該動作の周期に基づく複数周期にわたって超音波送受信部に超音波を送信させる。【選択図】図5
