When the stiffness of the skeletal muscle is evaluated, the cell structure anisotropy becomes a problem. Then, this research aimed at the analysis and the evaluation of the organization anisotropy by MRE. We had examined two mainly. At first, the change in the frequency of the wave was analyzed by an isotropic structure as an anisotropic structure. Stiffness was similarly analyzed. It ..scorching.. was suggested it was necessary to consider anisotropy when MRE was analyzed enough.
