ABSTRACT:
An ultrasonic blood flow imaging method for two-dimensionally displaying the velocity distribution of blood flow within a body to be examined is characterized in that the velocity distribution is displayed as a color picture in which the velocity direction is represented by one color when positive and by another different color when negative, and the magnitude of the velocity is represented by varying the brightness of the color concerned. An ultrasonic imaging apparatus for carrying out this method comprises an ultrasonic transmitter/receiver which outputs a tomographic image signal corresponding to a specific region of an object, and an average velocity signal and a velocity deviation signal corresponding to the velocity of blood flow within the specified region. These signals are stored in respective frame memories and then processed by a color processor to produce a color video signal which is input to a color display for displaying a tomographic image, and the velocity and velocity deviation of the blood flow.
