Abstract
An evaluation range decision unit analyzes reception beam data before detection processing out of reception beam data to decide an evaluation range excluding at least a part of a structure of a subject in a data space of the reception beam data. An attenuation amount estimation unit estimates an attenuation amount of ultrasound waves in the subject based on a frequency spectrum of the reception beam data of each region included in the evaluation range among a plurality of regions arranged in a depth direction defined in advance in the data space of the reception beam data. An image formation unit executes TGC processing as brightness correction processing based on the attenuation amount of the ultrasound waves estimated by the attenuation amount estimation unit.
