Every year, a quite large number of people die from cardiac and cerebrovascular diseases that are related to arteriosclerosis. Arteriosclerosis shows symptoms only in the advance stage, and hence it is vital to diagnosis it at an early stage. In this study, a technique has been developed to measure non-invasively the in vivo elastic modulus of human common carotid artery (CCA) using ultrasound. Pulsatile diameter change and mean diameter of the common carotid artery were measured with the ultrasound device. In vivo elastic modulus E-m vjvo was calculated from pulsatile diameter change, diameter, and pulse pressure. It is found that the in vivo elastic modulus of common carotid artery is a useful marker of the development of the arteriosclerosis.
