Color Doppler Imaging

Journal of Diagnostic Medical Sonography, 1992
Color Doppler instruments provide gray-scale imaging with two-dimensional flow in real time. Velocity information is encoded in color. Color Doppler imaging parameters, including packet size, color gate, color gain, color reject, capture function, velocity map, and velocity tag, are described.
