1. An operation method of an ultrasound diagnostic apparatus, comprising:
executing one or more imaging series of steps with a plurality of ultrasound transducers to acquire an ultrasound image to perform an ultrasound diagnosis; and
applying a polarization processing to the plurality of ultrasound transducers in a non-diagnostic period within each frame time during an execution period of the ultrasound diagnosis by executing the one or more imaging series of steps,
wherein the non-diagnostic period 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 the ultrasound diagnosis are not performed, within the each frame time in which an image of each frame of the ultrasound image is acquired during the execution period of the ultrasound diagnosis,
wherein, within one frame time in which an image of one frame is acquired by a plurality of scanning lines scanned by electronic sector scanning for performing the ultrasonic diagnosis using the plurality of ultrasonic transducers, the non-diagnostic period is a period from an end of scanning of a last scanning line of the plurality of scanning lines to a start of scanning of a first scanning line within a next one frame time, and
wherein the polarization processing is separate from the one or more imaging series of steps.
