摘要

　An ultrasonic diagnostic device wherein the state of tissue in the body can be observed for prescribed intervals. The ultrasonic diagnostic device has an ultrasonic wave transmission/reception unit and a control unit. The ultrasonic wave transmission/reception unit obtains biological information for a prescribed site of a subject by transmitting/receiving ultrasonic waves after being inserted into the body of the subject. The control unit causes the ultrasonic wave transmission/reception unit to transmit ultrasonic waves on the basis of a trigger signal that is periodically operated and that is set according to the state of the prescribed site, or a trigger signal that is obtained according to said state.
