PROBLEM TO BE SOLVED: To reduce the sense of incompatibility caused by the change in a display color in a region where a turnover phenomenon occurs. SOLUTION: In an ultrasonic diagnostic device 200, a CFM process section 14a calculates a blood flow velocity V and the varianceσof the blood flow velocity V. A differential calculation section 4a outputs the function value f(ΔV,σ) including the differenceΔV between the blood flow velocity V corresponding to the latest frame and the blood flow velocity Vτstored in a frame memory 3 and the varianceσ. A DSC 5a generates the CFM image data for displaying a CFM image in the same display color at least in a large-velocity region or in a display color giving little sense of incompatibility even if a region with a different flow direction is adjacently displayed for a flow region with a large function value f(ΔV,σ), thereby an offensive display is eliminated, and an obvious screen is obtained. |
