Reconstruction of a patient-specific surface model of the humerus bone

Abstract

This paper takes the reader into the field of reconstructing a missing distal region of a 3D humerus model, partially reconstructed from CT scans, using a mean model. As clinicians utilize modern medical imaging methods, some of them utilize X-rays, which are deemed to be harmful for the patient. Therefore, CT scans are usually limited to only the region necessary for the diagnosis. On the other hand, the clin- icians need to gather as much imaging data as possible to enable exploring new possibilities, for instance biomechanical analysis, patient specific bone reconstruc- tion surgery planning, and personalized implant design. The goal of this thesis is to propose a new approach to reconstructing the full 3D surface model of a patient- specific humerus bone based on a partial model rendered from a typical shoulder CT scan showing only the proximal humerus.
