Abstract

A computer model of a tapered blood vessel was developed to investigate the effects of arterial stenosis on pulse transmission properties. Significant increases in phase velocity (C_ph), characteristic impedance (Z_O), and local reflection coefficients (Γ_L) were found with increasing severity of the stenosis
