A reception data array composed of a plurality of items of reception data corresponding to a plurality of transmission/reception conditions is generated. For each of the plurality of items of reception data, a plurality of units of data processing are applied to that item of reception data according to a plurality of data processing conditions. A blood flow data set is thereby generated from the reception data array. By evaluating the blood flow data set, an optimum transmission/reception condition and an optimum data processing condition are determined.

Ultrasound diagnostic apparatus and operation condition setting method

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.
