Description:

The velocity and direction of blood flow can be measured from the Doppler shift of ultrasound waves. The Doppler effect refers to the change in sound frequency when reflected from moving objects; objects moving towards the source reflect the sound with a higher frequency and objects moving away with a lower frequency. By comparing the initial and reflected signals, the shift can be calculated and characteristics of object movement inferred.
