Abstract
The present application relates to a blood flow image forming apparatus and a computer-readable non-transitory storage medium. A Doppler processing section (40) generates a Doppler signal based on a reception beam data string obtained by transmission and reception of an ultrasound wave with respect to an object. A two-dimensional data space is constituted by the reception beam data string. A distribution data operation section (42) operates at least one of a power of the Doppler signal, a velocity of a tissue in the object, or a variance of the velocity of the tissue in the object with respect to each data element in the two-dimensional data space based on the Doppler signal. A discrimination index map generation section (44) generates a discrimination index map that characterizes a degree of certainty of a blood flow region A in the two-dimensional data space constituted by the reception beam data string based on distribution data of each ROI (52) set in the two-dimensional data space. A blood flow image formation section (46) forms a blood flow image in which a halo artifact is reduced based on the Doppler signal and the discrimination index map.
