Abstract

Systems and methods for enhancing spatial specificity and increasing effective image acquisition speed by performing flow processing on channel data for application of nonlinear beamforming are provided. The method includes generating clutter filtered signals, delaying the clutter filtered signals to provide delay aligned clutter filtered signals, calculating coherency of the delay aligned clutter filtered signals, and nonlinearly combining the delay aligned clutter filtered signals and the coherency of the delay aligned clutter filtered signals across each transducer element at one or more depths to generate at least one beamformed signal for each received set of echo signals in a sequence of echo signals at the one or more depths. The method includes calculating and presenting a measurement for the one or more depths based on the at least one beamformed signal for each received set of echo signals in the sequence of echo signals at the one or more depths.
