Abstract: Provided are a control method of an ultrasound diagnostic apparatus and an ultrasound diagnostic apparatus capable of improving detection accuracy of a target inside a subject. An ultrasound diagnostic apparatus includes: an ultrasound probe; an image acquisition unit that acquires an ultrasound image of a subject using the ultrasound probe and in accordance with a plurality of parameters related to image acquisition; a specific target detection unit that detects a specific target from the ultrasound image using a machine learning model; and a preset setting unit that sets and supplies different presets to the image acquisition unit during an operation and during a non-operation of the specific target detection unit for a predetermined preset among the plurality of parameters.

Abstract: In an ultrasound diagnostic apparatus and a display method of the ultrasound diagnostic apparatus, a body mark in an orientation corresponding to an examination location of one lung of a subject, indicating the examination location in the one lung, is displayed on a monitor, and in a case of switching from the one lung to the other lung by a left and right switching button, a body mark in an orientation corresponding to an examination location of the other lung, indicating the examination location in the other lung, instead of the body mark of the one lung, is displayed on the monitor.

Abstract: In an ultrasound diagnostic apparatus and a display method of the ultrasound diagnostic apparatus, a first display region including an ultrasound image of one lung of a subject captured using an ultrasound probe, a second display region including a plurality of examination location selection buttons for selecting one examination location as an examination target location from among a plurality of examination locations in the one lung, and a third display region where a first display screen including a freeze button is displayed are displayed on a monitor. In a case where the freeze button is selected, instead of the first display screen, a second display screen including a plurality of diagnostic finding buttons corresponding to a plurality of predetermined diagnostic findings is displayed in the third display region.
