PROBLEM TO BE SOLVED: To eliminate the compromise necessary for an already known system, to visualize the dynamics of a rapid flow, and to separate the image of a flow area from the image of a wall or a structural area. SOLUTION: An ultrasonic image pick-up system for displaying a color flow image includes a receiver 14 to generate the color flow signal corresponding to a frame obtained from the stimuli of converter 11 of a different number from the number of the pulse repetition ratio different from each other at every beam position. The color flow signal is selected and coupled so as to visualize the flow dynamics of the liquid (such as blood), and maintain the segmentation of the liquid flow from other structures. |
