An ultrasound imaging system includes a transducer array (102) having a plurality of transducer elements (106) for generating an ultrasound signal, receiving echo signals generated in response to the ultrasonic signal interacting with a stationary structure and a moving structure, and generating are formed by indicative electrical signals of the echo signals. The system further includes a beamformer (112) configured to process the electrical signals and to generate time sequences of beamformed data. The system further includes a filter (118) configured to process the beamformed data and to remove or replace a set of frequency components based on a threshold to produce corrected beamformed data. The system further includes a flow processor (120) configured to estimate a velocity of the moving structure from the corrected beamformed data. The system further includes a rendering unit (224) configured to display the flow velocity estimate on a display (124).
