The ultrasonic diagnostic apparatus of the present invention is an ultrasonic diagnostic apparatus to which a probe having a transducer can be connected. The ultrasonic diagnostic apparatus drives the probe 1 to transmit ultrasonic waves to a subject； A reception process that generates a reception signal based on reflected ultrasound from the subject received by the toucher, and when a predetermined condition based on the reception signal is satisfied, at least the transmission process and the reception process A controller 100 that performs an automatic freeze process for stopping any one of them is provided, and the controller 100 suppresses the automatic freeze process for a predetermined period after receiving a predetermined operation event.本発明の超音波診断装置は、振動子を有する探触子が接続可能な超音波診断装置であって、探触子１を駆動して被検体へ超音波を送信する送信処理と、前記探触子によって受信した前記被検体からの反射超音波に基づく受信信号を生成する受信処理とを行い、前記受信信号に基づく所定の条件が満たされた場合に、前記送信処理および前記受信処理の少なくともいずれか一つを停止する自動フリーズ処理を行う制御器１００を備え、制御器１００は、所定の操作イベントを受け付けてから所定の期間、自動フリーズ処理の抑制を行う。
