Abstract
The present invention relates to a method and apparatus for performing motion adaptive frame averaging for ultrasound color flow images used to overcome lag and smearing alias of color due to motion. One embodiment of the present invention comprises an ultrasound machine for generating an color flow imaging responsive to moving tissue. The ultrasound system comprises a front end and at least one processor. The front-end is arranged to transmit ultrasound waves into the moving tissue, generating received signals in response to the ultrasound waves backscattered from the moving tissue. The processor is responsive to the received signals, calculating a motion factor by comparing at least one current b-mode frame with at least one previous b-mode frame, determining motion using at least the motion factor, increasing a level of frame averaging if the motion factor is below a first predetermined threshold, and decreasing the level of frame averaging if the motion factor is above a second predetermined threshold.
