Ultrasound diagnostic apparatus and control method of ultrasound diagnostic apparatus

Abstract

Provided are an ultrasound diagnostic apparatus and a control method of an ultrasound diagnostic apparatus that can easily and accurately select an ultrasound image of a frame suitable for measuring a diameter of a left ventricular outflow tract. The ultrasound diagnostic apparatus that guides a frame suitable for measuring a diameter of a left ventricular outflow tract from ultrasound images of a plurality of frames in which a heart of a subject is imaged includes an image recognition unit that performs image recognition on a local anatomical structure of the heart in each of the plurality of frames, a time-varying waveform generation unit that generates a time-varying waveform of an anatomical structure state based on the local anatomical structure recognized by the image recognition unit, a candidate frame extraction unit that extracts a measurement candidate frame from the plurality of frames using the time-varying waveform, a monitor, and a display controller that displays the measurement candidate frame in a highlighted manner on the monitor.
