Abstract :
A method for displaying a 2-D intracardiac blood flow vector is presented. The flow velocity along the beam is measured by a color Doppler device, and the 2-D velocity vector is estimated by a method based on the continuity equation in flow mechanics. The experimental results show that the system is effective for determining the intracardiac blood flow state
