Claims (1)

[Scope of Claim for Utility Model Registration] An ultrasonic Doppler device capable of displaying images of average blood flow velocity and dispersion in a superimposed manner, wherein the sum and difference of the average blood flow velocity and dispersion are respectively dispersively displayed. A digital calculation means calculates the upper and lower limits of the area as data, and the sum and difference data calculated by this digital calculation means as well as the average blood flow velocity data are compared with the address data for writing into the image memory. , a comparing means for outputting first, second, and third matching signals when the address data matches each of the data, and first, second, and third matching signals output from the comparing means.
An ultrasonic Doppler device comprising: brightness selection means for outputting a signal that gives a different brightness level depending on the combination of each matching signal;
