Original Abstract Submitted

An ultrasound diagnostic apparatus includes an information processing unit executes processing of acquiring spatial frequency distribution data in a depth direction for Doppler image data, and processing of performing filter processing, which is based on filter characteristics determined in accordance with the spatial frequency distribution data and characteristics of the transmitted ultrasound, on the Doppler image data. The information processing unit searches for a spatial frequency corresponding to a maximal value of a distribution indicated by the spatial frequency distribution data in a search range determined in accordance with a pulse width, and obtains characteristics for suppressing a level of the spatial frequency distribution in a spatial frequency band including the spatial frequency that is searched for.
