Abstract

Estimates of the average velocity and turbulence of blood flow are determined by weighting the instantaneous frequencies of a returning Doppler signal. The weighting can be chosen so that the estimates are optimized. The weighting can be chosen so as to duplicate the algorithm of other ultrasound flow imaging systems.
