Abstract
The array of reception beam data sets obtained by transmitting and receiving ultrasonic waves to and from a subject constitutes a two-dimensional data space. Based on the Doppler signals, a distribution data calculation unit calculates, for each of data elements in the two-dimensional data space, at least one of power of the Doppler signal, the velocity of tissue in the subject, and the velocity dispersion of tissue in the subject. A discrimination index map generation unit generates a discrimination index map indicating the likelihood of being a blood flow region A in the two-dimensional data space composed of the array of reception beam data sets, based on distribution data that are set for each of regions of interest in the two-dimensional data space. Based on the Doppler signal and the discrimination index map, a blood flow image forming unit forms a blood flow image with reduced blooming artifacts.
