A method includes receiving ultrasound echo signals produced in response to a pulsed ultrasound field interacting with anatomical tissue and flow of structure therein. The method further includes generating electrical signals indicative thereof. The method further includes beamforming the electrical signals producing beamformed data. The method further includes constructing a real-time image of the anatomical tissue with the beamformed data. The method further includes constructing a de-aliased color images of the flow with the beamformed data. The method further includes visually presenting the real-time image of the anatomical tissue with the de-aliased color images of the flow superimposed thereover.
