Parametric Estimation of Mean Frequency and Spectral Variance in Color Flow Imaging
Color Doppler imaging for the diagnosis of cardio-vascular diseases has become a widely applied technique in recent years. Fast and efficient techniques capable of evaluating blood flow characteristics using a few signal samples are required for real-time bi-dimensional mapping of blood velocity, flow direction and turbulence. In a Color Doppler system the above three parameters are color coded and superimposed on a morphologic image obtained using a standard echographic technique (B-mode).
