Abstract
A color imaging display method and apparatus in a color doppler imaging system can display a high quality of a color image in which a flash artifact which is a kind of a clutter signal is removed. The method and apparatus determines whether the flash artifact exists, according to the result obtained by frequency-estimating a doppler signal where an ultrasonic signal is filtered and a clutter signal where the ultrasonic signal is not filtered, and mixing the information obtained through the frequency estimation, and determines whether or not a corresponding pixel is displayed in an ultrasonic color doppler image. Thus, the pixel which has been determined as the flash artifact is not displayed, to thereby obtain a high quality of a color image.
