1. A method for twinkle artifact suppression in color flow, the method comprising: acquiring color flow ultrasound data representing a patient; detecting a twinkle artifact represented in the color flow ultrasound data from the color flow ultrasound data, the detecting being a function of a decorrelation over time and spatial variance; suppressing the twinkle artifact in the color flow ultrasound data; and generating a color flow image with the color flow ultrasound data after the suppressing.
