Abstract

This thesis comprises three studies that aimed to develop, validate and demonstrate the application of two methods to estimate accurate segmental inertial parameters using mass distribution data from dual-energy X-ray absorptiometry (DXA). The DXA/Vol method produced a rigid volumetric template of the body under a uniform density assumption. The DXA/3D method produced an inertial system of particles within a volumetric domain created with surface scanners. The studies demonstrated the accuracy and the greater expediency of both methods in comparison to alternative medical imaging methods. Moreover this thesis provides the foundation to expand the application of these methods in biomechanical research.
