Abstract
An ultrasonic diagnostic apparatus displays a moving body in colors. Particularly to ultrasonic analysis equipment that provides frequency and sign outputs corresponding to blood flow speed and direction by means of a color flow mapping analyzer. The average of signs analyzed by a color flow mapping analyzer is calculated to select the average sign or the sign as the result of analysis. The selection conditions are that the frequency analyzed by the color flow mapping analyzer is below is a given value and the strength analyzed thereby is below a given value. If both or any of the two conditions are met, the average sign is selected. Otherwise, the sign itself is selected. The speed distribution of a moving body is displayed on the basis of the average of selected signs and the frequency analyzed by the color flow mapping analyzer, whereby effects of noises contained in analyzed signs can be eliminated considerably.
