Abstract: In the ultrasound diagnostic apparatus, the ultrasonic wave transmitter/receiver transmits and receives an ultrasonic beam to a subject to generate reception data; the delay correction unit corrects a delay time of the reception data to align a phase of the reception data; the reception aperture level setting unit sets two or more reception aperture levels of reception data from reception data after correction of the delay time; the image producer produces ultrasound images corresponding to the set reception aperture levels, by performing phase matching addition on the reception data after correction of the delay time; and the image quality determination unit determines image qualities of the ultrasound images corresponding to the set reception aperture levels and selects an ultrasound image having a predetermined image quality.
