ABSTRACT:
An ultrasound imaging system of the type having a receive beamformer that acquires multiple receive beams from each respective transmit beam includes an azimuthal spatial filter which operates to correct for geometric distortions typically associated with such multi-beam imaging systems. This azimuthal spatial filter is responsive to input signals derived from the receive beams to generate a corrected signal output as a function of a selected set of receive beams and a set of filter weights. The filter weights are caused to vary in accordance with the azimuthal coordinates of the selected receive beams in order to improve performance.
