Ultrasound diagnostic apparatus and ultrasound measurement method using same

Abstract

An ultrasonic diagnostic apparatus according to the present disclosure is configured so that a probe including transducers is connectable thereto and performs predetermined measuring processing on a subject's 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 probe's 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 to perform predetermined measuring processing on the region of interest.
