Ultrasound diagnostic apparatus and method of controlling ultrasound diagnostic apparatus

Abstract

Provided are an ultrasound diagnostic apparatus and a method of controlling an ultrasound diagnostic apparatus that can provide support for accurate measurement of cardiac function with a simple apparatus configuration. An ultrasound diagnostic apparatus includes: an image acquisition unit that acquires ultrasound images of a plurality of frames in which a heart of a subject is imaged using an ultrasound probe; a contour extraction unit that extracts a contour of a cardiac chamber from each of the ultrasound images of the plurality of frames; a contour correction unit that performs correction processing on a plurality of contours of the cardiac chamber extracted from the ultrasound images of the plurality of frames such that the plurality of contours of the cardiac chamber smoothly change in time series; and a display controller that displays the ultrasound image on which the contour of the cardiac chamber extracted for each frame is superimposed, on a monitor in real time, and that displays the ultrasound image on which the contour of the cardiac chamber on which the correction processing is performed is superimposed, on the monitor.
