Abstract

Noninvasive measurement of the arterial wall shear rate has been studied in many works, in relation with the various mechanical factors involved in atherosclerosis genesis (Nerem [1], Noller [2]). In a previous work (Bensalah, [3]), it has been shown how to compute reliably this factor in the case of a linear newtonian flow. This method required the only measurement of the arterial centre line velocity, by means of the ultrasonic Doppler velocimetry. Furthermore it avoided the use of curve fitting methods (Lou, [4]), inefficient because of the rat
