Abstract:
A method of displaying a color image in a color Doppler imaging system, the color image displaying method comprising the acts of:(a) filtering E clutter signal from an ultrasonic signal reflected from an object; (b) analyzing a respective frequency spectrum of the non filtered ultrasonic signal and an ultrasonic Doppler signal filtered in act (a), to thereby calculate clutter information and Doppler information; (c) determining whether a flash artifact exists based on the clutter information and the Doppler information calculated in act (b); (d) outputting pixel display information in such a manner that a corresponding pixel is not displayed if it has been determined that the flash artifact exists and the corresponding pixel is displayed if it has been determined that no flash artifact exists in act (c); and (e) displaying an ultrasonic color Doppler image according to the pixel display information of act (d).
