| Abstract(in English) | In order to evaluate patient's knee motion, 3-D bone model-based approaches are employed by combining a fluoroscopic image sequence of the knee and its 3-D model. For bone model construction, the MR system is used currently because it is less invasive to the patient than CT. A single problem is that a conventional anatomy coordinate system defined by the entire femur cannot easily be determined because it takes enormous amount of time to image the entire femur. Then, we proposed an iterative method of determining an anatomical coordinate system defined solely by the femoral condyle. Subsequently, we evaluated the positional relationship between the proposed and conventional systems. Empirical results demonstrated that 1) the proposed coordinate system could be determined in all cases as expected and 2) its position and orientation seemed relatively stable with respect to the conventional system. |
