Ultrasound Diagnostic Apparatus And Control Method Of Ultrasound Diagnostic Apparatus

An ultrasound diagnostic apparatus that receives a reception signal representing reflection waves from an ultrasound probe, the ultrasound probe including:

• a plurality of transducers disposed along a first direction and configured to transmit an ultrasound beam to a subject and receive reflection waves thereof, and
• a transducer switching section configured to control a driving signal to the transducers to deflect a transmission direction of the ultrasound beam to the first direction, the ultrasound diagnostic apparatus comprising:
• a first position specifying section configured to specify a depth of a detection object inside the subject based on a temporal variation of the reception signal;
• a second position specifying section configured to specify a position of the detection object in the first direction based on reception signals generated based on reflection waves from the detection object obtained with the ultrasound beams transmitted at a first angle and a second angle which are different from each other in a transmission direction of the ultrasound beam;
• and
• an output control section configured to output the position of the detection object in the first direction such that an operator of the ultrasound probe is allowed to identify the position of the detection object in the first direction.
