Tissue components within atherosclerotic plaques were classified by intravascular ultrasound (IVUS) images and were analyzed using finite element method (FEM) to assess the stress distribution within the plaque. Young's elastic modulus for FEM was given to each tissue based on the values of sound speed and density obtained using scanning acoustic microscopy. The Young's modulus was highest in the calcification and lowers in the lipid. The first principle stress was concentrated to the site with relatively low elastic fibrous cap.
