ULTRASONIC DIAGNOSIS DEVICE AND METHOD FOR CONTROLLING ULTRASONIC DIAGNOSIS DEVICE

An ultrasound diagnostic apparatus and a control method of an ultrasound diagnostic apparatus that enable a user to clearly check whether or not a breast of a subject is sufficiently scanned are provided. An ultrasound diagnostic apparatus 1 includes a sensor 4 that detects an inclined angle or a height position of an ultrasound probe 2, an image generation unit 13 that generates an ultrasound image from a reception signal obtained by scanning, a scanning detection unit that detects a start point and an end point of scanning of a breast of a subject from an inclined angle or a height position of the ultrasound probe 2, a graph generation unit 17 that generates a graph of a change in the inclined angle or the height position detected from the start point to the end point and that displays the graph on a monitor 15, and a display image selection unit 19 that, in a case where at least one of a designation point on the graph corresponding to the start point or a designation point on the graph corresponding to the end point is designated by a user, displays an ultrasound image of an imaging position corresponding to the designation point on the monitor.
