摘要： 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.

摘要： Based on at least one of a degree of variation in brightness values of pixels or a representative brightness value of frame data for evaluation range decision for each region defined in a data space of frame data, each region is classified into a region that is included in an evaluation range and a region that is not included in the evaluation range. An attenuation amount estimation unit estimates an attenuation amount of ultrasound waves in a subject based on a frequency spectrum of reception beam data of each region included in the evaluation range among a plurality of regions arranged in a depth direction, the region being defined in a data space of the reception beam data and corresponding to each region defined in the data space of the frame 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.

摘要： A characteristic estimation unit analyzes a reception signal before detection processing among reception signals obtained by transmitting and receiving ultrasound waves with respect to a subject, to estimate a signal characteristic of the reception signal for each region in a data space of the reception signal. An image processing parameter decision unit decides an image processing parameter for enhancing an image quality of an ultrasound image based on the signal characteristic, for each region in the data space of the reception signal, which is estimated by the characteristic estimation unit. An image formation unit executes image quality enhancement processing of the ultrasound image based on the image processing parameter decided by the image processing parameter decision unit while forming the ultrasound image based on the reception signal after the detection processing.
