ULTRASONIC DIAGNOSTIC APPARATUS AND CONTROL METHOD FOR ULTRASONIC DIAGNOSTIC APPARATUS

PROBLEM TO BE SOLVED: To make it possible to easily place a probe in an appropriate position relative to a living body during an ultrasonic diagnosis.SOLUTION: An ultrasonic diagnostic apparatus is an ultrasonic diagnostic apparatus 100 configured connectable with a probe 1 having a plurality of oscillators. The ultrasonic diagnostic apparatus 100 comprises: an ultrasonic signal processing unit 2 which performs the transmission processing for generating transmission control signals to transmit ultrasonic waves from the probe 1 to a living body and the reception processing for obtaining reception signals based on reflected ultrasonic waves received by the probe; a flow rate analysis unit 4 which calculates the flow rate of a fluid flowing at least two measurement points in the living body, i.e. a first measurement point and a second measurement point in the living body, on the basis of the reception electric signals obtained from the probe; and a reliability judgment unit 5 which compares the flow rate of the fluid at the first measurement point with that at the second measurement point.
