Abstract

Tetrahedral finite element meshes with smooth surfaces can be created from computed tomography scans of cancellous bone in order to evaluate its mechanical properties. Image processing before creation of the mesh can affect the accuracy of determined mechanical properties. For a cancellous bone analogue, threshold, mesh density and surface smoothing parameters used in mesh generation were varied and the mechanical properties predicted by the resulting meshes compared to experimental results. This study has shown that threshold selection is vital for accurate determination of volume fraction and resulting mechanical properties. Smoothing of the surface also affects the local accuracy of the models.
