An ultrasonic diagnostic apparatus according to the present disclosure is configured so that a probe including transducers is connectible thereto and performs predetermined measuring processing on a subjects region of interest. The apparatus includes a controller, which performs transmission processing, in which an ultrasonic wave is transmitted toward the subject including the region of interest by driving the probe, and received signal processing, in which frames are generated based on the probes received signals representing the ultrasonic wave reflected from the subject including the region of interest, a number of times at mutually different times, thereby generating multiple frames, which selects at least two frames under measurement to be subjected to measurement from the multiple frames, which extracts measurable ranges, where the measuring processing can be carried out, based on respective received signals obtained from the region of interest represented in the at least two frames under measurement, and which combines those measurable ranges together co perform predetermined measuring processing on the region of interest.
