Abstract

Provided are an ultrasound diagnostic apparatus and a control method of the ultrasound diagnostic apparatus capable of easily correcting a segmentation result of a lumen of a heart in a short time.An ultrasound diagnostic apparatus includes: an image acquisition unit that acquires ultrasound images of a plurality of frames that are continuous in time series and in which a heart of a subject is imaged; a contour extraction unit that performs segmentation on the ultrasound images of the plurality of frames to extract a contour of a lumen of the heart for each frame; a cross-sectional area calculation unit that calculates a cross-sectional area of the lumen of the heart for each frame based on the extracted contour; a cross-sectional area change curve generation unit that generates a cross-sectional area change curve representing an actual temporal change of the cross-sectional area based on calculated the cross-sectional area; and an error detection unit that detects an error of the performed segmentation by comparing the generated cross-sectional area change curve with a predicted cross-sectional area change prediction curve.
