Abstract: A method and system for simulating, on a B-mode ultrasound simulator, a D-mode and C-mode Doppler ultrasound examination. Velocity and sound data describing blood flow at selected locations within blood vessels of a patient are gathered during an actual Doppler ultrasound examination. The gathered data are processed off-line to generate sets of flow velocity and sound values which describe blood flow at selected locations in a virtual B-mode frame buffer, and are stored in memory. Doppler simulation at a designated location on a the B-mode image generated from the virtual frame buffer is achieved by performing bilinear interpolation, at the time of simulation, from the data stored in memory, so as to determine flow velocity and sound values for all designated virtual frame buffer voxels.
