Abstract (in Japanese) (See Japanese page) 
(in English) The purpose of this study was to develop a method to analyze the pose of the knee nearthrosis mounted and to automate the registration procedure for easy use in clinical applications. The proposed registration method was essentially a model-based method, in which the CAD model was acquired by reverse engineering. The CAD model was converted into a two-dimensional image by a rendering technique, and the compatibility of the X-ray image and the image of the CAD model was investigated. To avoid the optimization of six unknown parameters with respect to the relative pose between the condyle and tibial models, a two-dimensional coordinate system was set on each component of the X-ray images. A three-dimensional coordinate system was also set on each of the two nearthrosis components. With such a setup, there was only one unknown rotational angle on each component, which was determined by an optimum algorithm in accordance with the contour error between the X-ray image and the image of the CAD model. Extensive computer simulation has been implemented to investigate the feasibility of the proposed registration method.
