Principle

This set-up shows how blood flow studies are performed using Doppler ultrasound (Doppler sonograph). On a realistic arm dummy, the differences between continuous (venous) and pulsating (arterial) flow are shown as well as the difference in flow through a normal blood vessel and a stenosis.

Benefits

Ideal experiment for medical students to learn the principles of Doppler sonography
True to life with an arm model with blood vessels and stenosis
Experiment components can also be used for other experiments relevant for medical students
Display of measurement values as with a diagnostic system

Tasks

Analyse blood flow and search positive and negative flow components. Explain the differences.
Locate the built-in stenosis and compare the spectral distribution upstream and downstream of the stenosis.
Examine and compare the three pulse modes of the pump.
