PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus which can be controlled in accordance with detailed movement of a probe.SOLUTION: An ultrasonic diagnostic apparatus includes: a reception part 20 generating a reception signal on the basis of ultrasonic waves reflected on a subject 18 and received by a probe 14 a movement detection part 30 detecting movement of the probe 14 on the subject 18 on the basis of the reception signal a contact determination part 42 determining whether or not the probe 14 moves away from the subject 18 and an instruction generation part 50 giving instruction to the ultrasonic diagnostic apparatus on the basis of the reception signal when rest of the probe 14 is detected, when the rest of the probe 14 on the subject 18 is detected and the non-contact determination that the probe 14 moves away from the subject 18 is detected after detection of the rest of the probe 14.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】探触子の詳細な動きに応じて超音波診断装置を制御できる装置を提供する。【解決手段】超音波診断装置は、被検体18で反射し探触子14で受信された超音波に基づく受信信号を生成する受信部20と、受信信号に基づいて被検体18上の探触子14の動きを検出する動き検出部30と、探触子14が被検体18から離れたか否かを判定する接触判定部42と、被検体18上で探触子14が静止したことが検出され、探触子14が被検体18から離れたとの非接触判定が、探触子14の静止の検出後にされた場合に、探触子14の静止が検出されたときの受信信号に基づいて、超音波診断装置に指令を与える指令生成部50とを備える。【選択図】図1
