Which medical technique uses ultrasound waves reflecting off moving red blood cells to measure flow velocity?
Answer
Doppler ultrasound
Doppler ultrasound technique measures the velocity of moving objects, primarily blood flow, by assessing the frequency shift of ultrasound waves that reflect off moving red blood cells.
