Blood pressure pulse wave is propagated from heart to peripheral blood vessels with changing its waveform according to characteristics of pass way. Dynamic characteristics of total arteries have been investigated by wave equation on multi-branched arterial model. Some diseases, such as an abdominal aortic aneurysm, can be predicted by using the relation between the pulse waveform and arterial stiffness. The aim of this research is to propose a new method to detect such diseases based on the pulse wave propagation model on an arterial tree. In this paper, influences of tissue surrounding an artery, model of peripheral arteries and elasticity of arteries are investigated to elaborate a multi-branched arterial model of human body.
