A study on the fitness measurement of artificial femur through medical image processing

의료영상처리를 이용한 인공고관절 정합도 측정 방법에 관한 연구

In this paper, we studied a computer based three dimensional implantation system of artificial hip joint. The system can be utilized for doctors to select a suitable artificial femur which is best-fit for the patient and to find out the optimal implanting position as well. We proposed a new numerical index to measure the fitness between the artificial hip joint and the patient's femur. The proposed fitness index accounts for the variance of the distance between the outer contours of artificial hip joint and the femur in addition to the conventional area comparison. A few simulation are run to show results of fitness measurement and compared to the conventional method.
