Extension Set: Medical Doppler Sonography

A realistic arm model is used to simulate the application of the Doppler effect in medicine. With a Doppler sonography the influence of a stenosis on the flow profile can be investigated. A pump generates different flow types (continuous and pulsatile) and can simulate the human blood circulation. The measured Doppler signals can be presented acoustically as well as in a colour-coded Doppler spectrum. The results and images are similar to measurements of those on patients.
