Results of Micro-CT scanning and FEM analysis. By Micro-CT scanning, microstructures of the explant models could be observed in (A). 3D model was generated in Mimics as showed in B (solid model) and C (free meshed). Using Solidworks, 3D model of the scaffold could be generated from these elements (D and E). By finite element (FEM) analysis, strain distribution results of group 1000 μϵ, 2000 μϵ and 3000 μϵ were shown respectively in F, G and H.
