とする超音波診断装置。[Claim for Utility Model Registration] An image memory that stores tomographic image data obtained based on ultrasound echoes, average blood flow velocity data and dispersion data obtained based on ultrasound Doppler, and from this image memory. It is equipped with a color lookup table memory in which a color code that gives a predetermined hue to each read data is set, and the tomographic image, average blood flow velocity, and dispersion data are superimposed on the same screen. In an ultrasonic diagnostic device that displays in color, there is a dispersion threshold setter that sets a dispersion threshold in advance, and a dispersion threshold setter that sets a dispersion threshold in advance, and a value obtained based on the threshold set by the dispersion threshold setter and the transmission and reception of ultrasonic waves. Based on the comparison result of this distributed data comparator, if the value of the distributed data is larger than the threshold value, the distributed data is prioritized over the average blood flow velocity data. an ultrasonic diagnostic apparatus comprising: a selection circuit for selectively outputting data; and the color lookup table memory is set to a color code that gives a single hue to distributed data.
