Abstract (in Japanese) (See Japanese page) 
(in English) Segmentation of the diseased hip is a prerequisite for patient-specific simulation for hip surgery.
Accurate boundary determination of the femoral head and acetabulum is the primary challenge in diseased hip joints.To overcome this difficulty, we investigated a multi-stage method in which the hierarchical hip statistical shape model (SSM) is initially utilized to complete segmentation of the pelvis and distal femur, and then the conditional femoral head SSM is used under the condition that the regions segmented during the previous stage are known.
Finally, graph-cut refinement is performed.
CT data from 100 diseased patients categorized on the basis of their disease type and severity, which included 200 hemi-hips, were used to validate the method.
