ABSTRACT:
A reference condition generation unit of an ultrasonic diagnostic apparatus generates a reference delay condition and a reference amplitude condition for determining delay time and amplitude of a driving pulse to be supplied to a transducer element at the time of non-simultaneous and parallel reception. A transmission condition generation unit generates a transmission delay condition and a transmission amplitude condition for determining delay time and amplitude of a driving pulse to be supplied to a transducer element at the time of simultaneous and parallel reception, on the basis of the reference delay condition and the reference amplitude condition. A transmission unit sets the delay time and the driving amplitude of the driving pulse to be supplied to a plurality of adjacent transducer elements selected by an element selection unit among the transducer elements arranged in an ultrasonic probe, on the basis of the transmission delay condition and the transmission amplitude condition.
