Functional Imaging of the Proximal Femur Using Shape Template and a Bone Mineral Density Image (original) (raw)

This research presents a method for estimating the 3D geometrical shape and internal architecture of the proximal femur using a single 2D bone mineral density (BMD) image and a shape template. The study involved the analysis of eighteen human cadaver femurs, revealing that the method yielded small errors in geometrical parameters and achieved moderate accuracy in volumetric BMD estimation. The findings indicate that the proposed method enhances predictions of bone geometry and strength compared to previous approaches, potentially improving fracture risk assessments.
