| Outline of Final Research Achievements |
In order to investigate the kinematics and contact behavior at the knee joint, a novel 2D to 3D image matching technique utilizing MRI volume rendering of the knee was established. This technique can eliminate both the laborious task of contour extraction from bone in MR images and the radiation dose issue. Also, an assessment system for 3D weight-bearing alignment of the lower extremities using a slot radiography system was developed. This system produces high-speed full length X-ray imaging of the lower extremities while reducing patient exposure and small image distortion compared with conventional x-ray systems.
