Abstract

Pulse wave velocity (PWV) is widely used for estimating the stiffness of an artery. PWV is measured by the time of travel of the “foot” of the pressure wave over a known distance. This technique has a low time resolution and is an average measurement of artery stiffness between the two measuring sites. In this paper an external short pulse wave is generated noninvasively in the arterial wall by the radiation force of ultrasound. The impulse wave velocity in the artery is measured noninvasively with high time resolution over a short distance of a few millimeters.
