    Abstract

    the aim of this study is the characterization of carotid artery by analysis of blood-flow velocity waveforms. To characterise this vessel, we have estimate its transfer function and we have calculate noninvasively pulsatile and resistance index, after and before carotid bifurcation. The bloodflow velocity waveforms measured by phase contrast magnetic resonance imaging on 20 subjects. Our results showed that the transfer function is a second order for a young subjects (22±2ans) and is a first or second order for an aged subject (>60 years) it confirms that with age the arterial rigidity increases.
