Abstract :
Basic velocity measurements from a previously reported study of modeled carotid artery bifurcation disease are postprocessed to derive indices potentially useful for clinical diagnosis. Selected parameters are based upon ultrasound pulse Doppler velocity measurements made at sites ±0.625 radius at axial distances of 0, 1, 3, 5, and 10 diameters downstream of smooth axially symmetric constrictions of 0%, 20%, 40%, 60%, and 80% diameter reduction
