Generation of 3D shape, density, cortical thickness and finite element mesh of proximal femur from a DXA image
3D shape, vBMD and FE mesh of the proximal femur were reconstructed from a DXA image. Surface reconstruction error was 1.0?1.4mm. Use of DXA, instead of projected CT images, had no significant effect on the reconstruction accuracy. DXA-based FE agreed well with CT-based FE analysis (stiffness r2=0.85, MAC=0. 0.977). DXA-based FE analysis may help to simulate patient-specific bone mechanics.
