An optimized methodology for estimating patient-specific joints’ poses

Yahia-Cherif, L. and Magnenat-Thalmann, N.

Abstract: In this paper, we present a methodology to estimate and visualize bone poses of patient-specific hip joints while minimizing the effects of the skin artifacts by combining two non-invasive methodologies: Magnetic resonance Imaging (MRI) and motion capture systems (Mocap). More precisely, this research focuses on two aspects: Firstly, we develop a methodology to reconstruct the 3D surfaces of the hip joint as well as its surrounding structures from medical imaging: We develop segmentation techniques to interactively generate anatomical 3D surfaces from Magnetic Resonance Images (MRI). Secondly, we simulate the joint motion with non invasive techniques. We combine two non-invasive methods: optical motion capture systems with medical imaging to estimate bone movement and assess the errors induced by the soft tissues deformation during motion.
