Ultrasonic Doppler effect Metal Low-poly 3D model

Using the Doppler Effect, it is possible to measure motions within the body. The ultrasonic flow meter is a medical device that can approximate the velocity of blood flow in a particular vessel. The transducer of ultrasonic flow meter is composed of both a transmitter and a receiver component. Ultrasonic waves of a set frequency (f0) are emitted by the transmitter, which are then scattered by the moving red blood cells (RBCs) that they come in contact with. These scattered waves return to the receiver with a frequency altered by the Doppler Effect .
