The incidence of circulatory diseases caused by arteriosclerosis is increasing with higher aged peoples in Japan. To diagnose arteriosclerosis on early stage, we introduce the elastic modulus concept which obtain from the relationship between the dynamic change in diameter and the inner presser. In this report, firstly, we examined the technique of the elastic modulus measurement using rubber tube specimen, then the system applied to common carotid artery of the body. The results showed that the elastic modulus (H-expression, Eq(2)) is useful for estimating arteriosclerosis.
