Combined Registration of Human Musculoskeletal System

Abstract

The need for accurate shape measurement and modeling of human musculoskeletal system appears to be important for both, clinical practice and incorporating emerging technologies to orthopedic and rehabilitation devices and systems. Particularly important emphasis is set on noninvasive, i.e. radiation-free approaches. The contemporary optical and probe-based measurement systems, together with 3D modeling and computer graphics techniques, provide the key platform for methodology development. We present the generic algorithm for reconstruction of patient’s back surface from clouds of points in the case of female spinal deformities. Basic registration methods that enable comparative analysis before and after applied therapy are described too. The key benefits of the global and local 3D registration methodology are shown through the matching analysis of the reconstructed surfaces and illustrated by the sample case study of spinal deformity diagnostics.
