Abstract: An ultrasound diagnostic apparatus (1) includes a frame thinning-out unit (8), a urinary bladder extraction unit (9), a feature quantity calculation unit (10), a candidate frame extraction unit (11), and a urine volume measurement unit (13). The frame thinning-out unit thins out ultrasound images of some frames from ultrasound images of a first frame group to form a second frame group of ultrasound images, the second frame group being constituted by a smaller number of frames than the first frame group of ultrasound images. The urinary bladder extraction unit extracts a urinary bladder region from each ultrasound image. The feature quantity calculation unit calculates a feature quantity of the urinary bladder region. The candidate frame extraction unit extracts, based on the feature quantity, an ultrasound image of at least one candidate frame from the ultrasound images of the second frame group.
