We present a robust and efficient standalone homogenised finite element pipeline from HR-pQCT clinical imaging data. Traditional voxel-based meshing techniques often struggle to accurately represent the complex geometry of cortical bone, leading to suboptimal mechanical simulations. To address this, our method leverages a smooth representation that significantly enhances the precision of cortical shell modelling, outperforming monophasic isotropic voxel-based meshes. By generating structured meshes, our approach ensures greater efficiency, reduced memory usage, and improved comparability across different patients or longitudinal studies. The algorithm integrates advanced image processing techniques, including contour extraction, BSpline smoothing, and mesh optimization, to produce high-quality meshes that accurately capture both cortical and trabecular compartments.
