Abstract
An information processing unit acquires spatial frequency distribution data in a depth direction for one frame in two-dimensional ultrasound image data of a plurality of frames constituting three-dimensional ultrasound image data, and performs filter processing, based on filter characteristics determined in accordance with the spatial frequency distribution data and characteristics of transmitted ultrasound in which each two-dimensional ultrasound image data is acquired. 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 of the transmitted ultrasound, 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.
