Abstract

To provide an ultrasonic diagnostic apparatus (100) that performs a synthetic aperture method using convergent transmission beamforming and is capable of changing configurations and process contents according to required calculation ability. An ultrasonic diagnostic apparatus (100) including a first phasing adder (1041) that generates a first acoustic beam signal by performing phasing addition on the sequence of reception signals for a plurality of observation points in a first target region including at least a portion of the target region; a parameter calculator (1043) that calculates a parameter based on the first acoustic beam signal; a second phasing adder (1042) that generates a subframe acoustic beam signal by performing phasing addition on the sequence of reception signals based on the parameter for a plurality of observation points in a second target region which is all or a portion of the target region; a synthesizer (1044, 1045) that generates a frame acoustic beam signal by synthesizing the subframe acoustic beam signals; a controller (108) that determines whether to generate the ultrasonic image based on any one of the first acoustic beam signal and the frame acoustic beam signal; and an ultrasonic image generator (105) that generates the ultrasonic image.
