Segmentation of the femur and pelvis from 3D CT data is prerequisite of patient specific planning and simulation for hip surgery. Separation of the femoral head and acetabulum is one of main difficulties in the diseased hip joint due to deformed shapes and extreme narrowness of the joint space. In this paper, we proposed initial region estimation method using probabilistic atlas (PA). We applied the proposed method to 22 datasets. Compared to the previous method, average distance was decreased about 50 % and 12 % for initial region estimation and segmentation result, respectively. In high dislocated hips, average distance was decreased about 44 %. The proposed method was shown to improve segmentation accuracy for datasets including high dislocated hips. We demonstrated that segmentation accuracy is improved using the initial region obtained with PA. |
