Twinkle artifact suppression in ultrasound color flow

摘要

Twinkle artifacts are suppressed in color flow. The color flow data itself, such as temporal decorrelation and spatial variance of the velocity and/or power, is used to identify the twinkle artifact. The aliased or high velocities caused by the twinkle artifact are suppressed, such as by reducing the velocity or by spatial filtering that adapts to the locations of the artifact. The powers caused by the twinkle artifact are suppressed.

主权项

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.
