Abstract
In the ultrasonic bloodstream imaging apparatus of the present invention, an ultrasonic wave is propagated into a subject, and a tomographic image of the subject is obtained. Then, a bloodstream data image is superimposed on the tomographic image and is displayed with color. A monochrome threshold value is set for tomographic image data obtained from an echo level of the ultrasonic wave. A color threshold value is set for bloodstream data obtained from the ultrasonic wave which has been affected by the Doppler effect. The echo level of the ultrasonic wave and the bloodstream data are compared with the monochrome threshold value and the color threshold value, respectively, and either a monochrome display mode or color display mode is selected based on the comparison result.
