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.
