Vector flow ultrasound imaging

An ultrasound imaging console, comprising:

• receive circuitry that receives a set of echoes produced in response to an ultrasound signal traversing blood flowing in a portion of a vessel in a field of view;
• a beamformer that beamforms the echoes, producing beamformed echoes;
• an image processor that generates an image based on the beamformed echoes;
• a velocity processor that determines flow direction and magnitude of the flowing blood based on the beamformed echoes;
• and
• a rendering engine that displays the image with graphical indicia representing the determined flow direction and magnitude superimposed thereover, wherein the graphical indicia includes different hues to indicate different flow directions and different intensities to indicate different flow magnitudes, and displays, concurrently with the image and the graphical indicia, a graphical 2D direction-magnitude map that maps the hues of the graphical indicia to directions and the intensities of the graphical indicia to magnitudes.
