The principles of color Doppler are similar to those of pulsed-wave Doppler. However, a larger region can be interrogated, and detected blood flow is assigned a color, typically blue or red, depending on whether the flow is moving toward or away from the transducer. Frequency shifts are estimated at each point at which motion is detected within an interrogated region, thus yielding information on direction of motion and velocity. Shades of blue or red are used to reflect the relative velocities of the blood flow. All stationary objects are represented on a gray scale, as in B-mode imaging. The benefit of color Doppler is that information on the direction and relative velocity of blood flow can be obtained. Color Doppler is limited by its dependence on the relative angle of the transducer to the blood flow.
