Abstract
A method and system for making visible a flow of blood in a living body. The method comprises the steps of obtaining blood flow vector distribution maps by a recpetion of waves reflected from a living body to which ultrasonic pulses are radiated, and by a Doppler analysis of the reflected waves, arranging dummy blood corpuscle in domains in which the blood flow vector distribution maps are expressed, calculating flow velocity vector of the dummy blood corpuscle for each dummy blood corpuscle from the blood flow vector distribution maps, forming a plurality of images in which the dummy blood corpuscles are sequentially moved in response to the flow velocity vectors, and sequentially displaying the plurality of the images on a display. Also, the density of the arrangement of the dummy blood corpuscles, for example, corresponds to the blood pressure.
