Statistical Shape Models and Atlases: Application to 2D-3D Reconstruction in THA
This chapter introduces both a statistically shaped model (SSM)-based surface model reconstruction method and an atlas-based intensity volume reconstruction method under the context of 2D-3D reconstruction-based planning for total hip arthroplasty (THA). It shows that, despite successful application of the SSM-based method for planning cup components to be used during THA, it has limitations regarding planning stem components because of missing information about intramedullary canal geometry. This deficit motivated us to develop an atlas-based intensity volume reconstruction method to derive the patient-specific intensity volume of the proximal femur, which facilitates precise planning of stem components.
