The study aimed to develop a three-dimensional motion analysis for natural knee joints with high precision in vivo using an image matching technique with a high-resolutional flat panel detector (FPD). Three-dimensional geometry data of the natural knee joint were reconstructed using computed tomography (CT) data. The reconstructed image was moved on a computer so that it could be matched to actual FPD image. However, the number of pixels in a whole reconstructed image was so huge. Therefore, in this study, several small windows were set up, in which a region of interest was determined to calculate instead of viewing the whole region of the image. The accuracy of the motion analysis method for the natural knee was confirmed using some X-ray images taken experimentally. High correlation was observed between the X-ray image and the computer simulating image.
