A 2D-3D reconstruction (Guoyan Zheng )) was used to generate 3D datasets from 2D DXA images. Those datasets are similar to genuine QCT images in terms of shape and intensity distribution and can be used for finite element analyses (FEA) of bones (a femur in this example). The FEA pipeline (Ghislain Maquer) starts with the meshing of the segmented bone and the definition of the boundary conditions (A). The bone density is then attributed to each element from the dataset and a load is applied (B). A material model interprets the local densities to simulate the elastic and damage behaviours of the bone tissue (C). The damage location matches the real failure pattern (D).
