Abstract (in Japanese) (See Japanese page) 
(in English) We developed a computer-assisted system for arthroscopic surgery, which is navigated by means of overlaying a 3D bone model reconstructed from CT images upon the arthroscopic image on a real-time basis. Such overlaying requires the positional relationship between the target bone in the actual space and the bone model in the virtual space. In order to obtain this relationship, we have employed a 2D/3D registration method, where two different fluoroscopic images taken in the directions perpendicular with each other were used. However, it is not necessary to use fluoroscopy in arthroscopic surgery. In order to apply this system to surgery, the development of a new registration method was required. Then, we developed an arthroscopic image-based registration method, where at least three different arthroscopic images of the articular surfaces and corresponding 3D cartilage-model reconstructed from MRI images are used. Experiments carried out under a surgical environment using a bone model revealed that the accuracy of the overlaying would be less than 1[mm] and less than 3[deg] on average in translation and rotation, respectively. In the next step, rotational accuracy should be improved to meet a clinical target, less than or equal to 1[deg] on average.
