Color Doppler

Color Doppler is an important complement to the two-dimensional image. It provides a visual multicolor display of the blood flow within the heart.

Doppler ultrasound is based upon the Doppler Effect. When the object reflecting the ultrasound waves is moving, it changes the frequency of the echoes, creating a higher frequency if it is moving toward the probe and a lower frequency if it is moving away from the probe. How much the frequency is changed depends upon how fast the object is moving. Doppler ultrasound measures the change in frequency of the echoes to calculate how fast an object is moving. Doppler ultrasound has been used mostly to measure the rate of blood flow through the heart and major arteries.

Color Doppler complements 2-D echocardiography and conventional Doppler techniques by providing color flow maps that improve the spatial characterization of flow disturbances.
