A new blood flow imager has been developed which presents a real-time two-dimensional (2D) image of blood flow superimposed on a real-time 2D anatomical image. The flow images are obtained by rapidly processing and displaying the returning Doppler signals from an entire 2D echo plane. The 2D Doppler information is encoded in color to represent the relative velocity and direction of flow. Blue represents flow toward the transducer and red represents flow away from the transducer. The intensity of the color varies with the relative velocity of the blood. The blood flow patterns obtained from parasternal and apical views in 12 normal subjects and 38 patients with valvular disease are listed.
