| Abstract: | The paper describes an in vitro study using a multi-gate Doppler ultrasound system to investigate flow disturbances in a blood analogue caused by small stenoses (2–25% cross-sectional area reduction), using steady flow (100–600 ml min−1) in a 6 mm diameter rigid artery model. The results indicate that stenoses greater than 5% were detectable. |
