Abstract
An ultrasonic color Doppler imaging system capable of discriminating an artery and a vein discriminates types of blood vessels such as the artery and the vein, and discriminatively displays the discriminated result on a display. The blood vessel types of the artery and the vein are determined using blood stream information according to a temporal change of a blood stream velocity pattern, and a different color is displayed according to the determined blood vessel type. Also, the brighter or darker color is displayed according to the blood stream velocity flowing in the blood vessel, to thereby provide accurate blood stream information.
