Abstract
An ultrasound system that includes a transducer configured to acquire ensemble channel/echo data and a filter bank configured to receive the echo data from the transducer, wherein the echo data is passed through a plurality of clutter filters within the filter bank to realize a plurality of echo data outputs. A processor calculates a spatial coherence value from each of the plurality of echo data outputs, compares the spatial coherence values of each filter, and selects the filter that yields a best spatial coherence for subsequent velocity estimation used to generate an output image for clinical use, where the best spatial coherence value is a highest and best spatial coherence value among the set of spatial coherence values.
