Femur 3D Reconstruction from MR images



Medical practice and life sciences take full advantage of progress in engineering disciplines, in particular the computer assisted placement technique in hip surgery. This paper describes a three dimensions (3D) model reconstruction approach from a sequence of magnetic resonance images (MRI) of human femur. This approach based in two steps: contour-detection and surface reconstruction provides digital 3D shape of the femur recognized by all CAD software. This model gives possibility to determine the bone axis with a good accuracy measurement of implant alignment during hip resurfacing or total hip arthroplasty, thereby reducing the risk of component mal-positioning and femoral neck notching.
