In an ultrasound diagnostic apparatus and a control method for an ultrasound diagnostic apparatus, a first ultrasound image of one pharyngeal part of left and right pharyngeal parts of a subject is analyzed to detect a region of a swallowing residue in the first ultrasound image. Registration of the first ultrasound image is performed with respect to a second ultrasound image of the other pharyngeal part of the left and right pharyngeal parts of the subject, and a region of the second ultrasound image corresponding to the region of the swallowing residue in the first ultrasound image in which the registration has been performed with respect to the second ultrasound image is determined. Then, a graphic including the region of the second ultrasound image is superimposed on the second ultrasound image and displayed on a monitor.

Ultrasound diagnostic apparatus and control method for ultrasound diagnostic apparatus

In an ultrasound diagnostic apparatus the of the present invention, a two-dimensional image generation unit generates a plurality of two-dimensional ultrasound images while shifting an angle or a position of a scanning plane using a transducer array in a state where an ultrasound probe is fixed by being in contact with an examination location of a subject. A motion determination unit sequentially calculates a similarity degree of at least two two-dimensional ultrasound images, and sequentially determines whether or not a motion of the ultrasound probe is within a predetermined reference value according to the similarity degree. Then, a three-dimensional image generation unit extracts the two-dimensional ultrasound images for which the motion of the ultrasound probe is determined to be within the reference value, to generate a three-dimensional ultrasound image, and a display control unit displays the three-dimensional ultrasound image on a monitor.
