Abstract

There are provided an ultrasound diagnostic apparatus and an operation method of an ultrasound diagnostic apparatus capable of performing polarization processing during the execution period of ultrasound diagnosis without affecting the image quality of an ultrasound image. In the ultrasound diagnostic apparatus and the operation method of the ultrasound diagnostic apparatus of the invention, a trigger generation circuit generates a trigger for starting polarization processing. After a trigger is given, during the execution period of ultrasound diagnosis, in a non-diagnosis period which is a period other than a period for acquiring an image of each frame and during which transmission of ultrasound waves and reception of reflected waves for performing ultrasound diagnosis are not performed, within each frame time in which an image of each frame of an ultrasound image is acquired, a control circuit performs polarization processing on a plurality of ultrasound transducers.
