Abstract
A color flow processor for color flow imaging of the velocity of scatterers flowing past slowly moving tissue. The processor has inputs for receiving basebanded signals derived from ultrasound reflected by the scatterers and by the slowly moving tissue; a wall estimator for processing the basebanded signals to output a wall frequency signal representing an estimated means Doppler frequency produced by the slowly moving tissue and a wall velocity signal representing an estimated velocity of the slowly moving tissue; a complex mixer for mixing the basebanded signal using the wall frequency signal so that the wall component is at DC and then outputting the mixed basebanded signals; and a flow estimator for processing the mixed basebanded signals and the wall velocity signal in an adaptive mode to output a flow velocity signal representing an estimated flow velocity of the scatterers which compensates for movement of the slowly moving tissue.
