| 摘 要： | IntroductionThe rupture of the anterior cruciate ligament( ACL) has become the most common knee in-juries.In operation of ACL reconstruction,thesurgeons have to find the optimal attachmentpoints resulting in a low anisometry of the graft,while preventing impingement between the graftand the femoral notch.Markus Fleute andStéphane lavallée1] proposed a real- time systemfor computer- assisted ACL surgery.A recentadvance in surgery is minimally invasive tech-nique that can avoid the large…

| Abstract: | A new scheme for femur shape recovery from volumetric images using deformable models was proposed. First, prior 3 D deformable femur models are created as templates using point distribution models technology. Second, active contour models are employed to segment the magnetic resonance imaging (MRI) volumetric images of the tibial and femoral joints and the deformable models are initialized based on the segmentation results. Finally, the objective function is minimized to give the optimal results constraining the surface of shapes. |
