Abstract
The volume of fluid flow within a vessel (VE) is measured by an ultrasound system. Ultrasound waves backscattered from the fluid within the vessel generate data from which velocity values representing components of velocity (V and V ) of the fluid flow in the scan plane (IP) are calculated. Grayscale data is correlated and the rate of decorrelation (D) of the data is calculated. The volume flow of the fluid (F) is estimated in response to the velocity signals and the rate of decorrelation (D).
