Claim One:
1. A method for generating a 3D knee joint image, comprising: generating a statistical shape model by using previously generated sample knee bone images; generating a knee joint bone image by segmenting a bone region from an input knee image using the statistical shape model; generating a knee joint cartilage image by segmenting a cartilage region from the knee joint bone image; and generating a 3D knee joint image for the input knee image by composing the knee joint bone image with the knee joint cartilage image, wherein the generating of the statistical shape model includes: generating matching images for each of the sample knee bone images by using original images and reduction images of each of the sample knee bone images; generating final matching images by using the matching images; generating feature point vectors for each of the sample bone knee images by extracting feature points of the final matching images; and generating the statistical shape model by using an average vector and a covariance matrix of the feature point vectors.
