Doppler ultrasound

The Doppler-effect has made possible the ultrasonic registration of the flow in blood vessels, because ultrasonic sound is reflected from red moving red blood corpuscles. Doppler ultrasonic diagnostics – Doppler flow investigation – has become a very valuable aid particularly in neurology and neurosurgery. The velocity and the direction of the blood flow are shown on a monitor as a visible movement and in shifting colours. The method is frequently used to determine blood pressure in newborn infants and anyone in whom the sounds normally heard are difficult to hear.
