A major problem in Doppler ultrasound has been the lack of quantitation of the magnitude of the blood velocity vector, particularly in intracardiac flow where the flow direction can't be estimated. This paper derives a new flow-mapping system for visualizing the two-dimensional blood velocity vector. The resultant velocity vector is the projection of the three-dimensional velocity vector on the beam scanning plane.
