[A versatile phantom for hemodynamic measurements with ultrasound Doppler equipment].

The test object described comprises a blood simulating liquid pumped through tubes embedded in tissue-mimicking material. The main components of the system can be realised in different ways. They are largely exchangeable with each other. Water, reticulated foam or silicone rubber is used as bulk background material, blood vessels are simulated using latex or silicone tubes or heat-shrink sleeving; in the artificial blood, sephadex particles or silicone emulsion were used as scatterers. The suspension of scattering particles is driven by a roller pump or a membrane dosage pump. The features of the components are described and the applications of the different phantoms discussed.
