The Difference Between Colour Doppler Velocity Imaging and Power Doppler Imaging [PDF]
European Heart Journal - Cardiovascular Imaging, 2002 The Doppler effect, which occurs on the reflection of ultrasound from moving blood or tissue, is observed as a shift in frequency of the reflected ultrasound from that of the incident ultrasound. This Doppler shift has been widely used in clinical practice as a means of measuring blood velocity.
