Abstract
An acoustic wave diagnostic apparatus and control method processing for transmitting an ultrasound pulse converging on a focusing position in the same direction of a subject from acoustic wave transducers to be driven, among a plurality of ultrasound transducers included in an ultrasound probe, while sequentially updating the acoustic wave transducers to be driven is performed multiple times for the same ultrasound transducers. An acoustic wave echo signal group is obtained by receiving an ultrasound echo of an observation target position in the ultrasound transducers. An autocorrelation operation is performed on a signal, which is obtained by correcting the positional deviation of an acoustic wave echo signal group based on the positional deviation between the focusing position and the observation target position, and an ultrasound echo signal without positional deviation, and a Doppler shift signal indicating the speed of the observation target position is generated.
