Constrained Registration of Multiple Rigid Objects in Close Proximity: Application in the Wrist Joint

Abstract

Current diagnosis of wrist joint problems is hampered by poor understanding of wrist joint functioning. To gain insight into the relationship between function and anatomy we aim at building a statistical shape model of the wrist. As a basis for the statistical model we intend to use CT scans of different individuals that are mutually registered to a common pose. Unconstrained registration of individual bones does not lead to an anatomically feasible arrangement of the carpal bones. We propose to use a constrained 3D registration, where bone movements are based on bone geometry and joint kinematics. Constrained co-registration of wrists from different individuals in different postures demonstrates that our method finds anatomically feasible wrists in the same posture that are therefore a sound basis for a statistical shape model.
