Abstract and keywords

The thorax is one of the segments frequently involved in road accidents. Various models of the human chest have been published to evaluate injury risks or to access innovative safety systems. The purpose of this study is to determine relevant parameters of the human ribcage (cortical thicknesses, cross section inertia...) to enrich FE models. This original method has been developed by combining CT-scan, 3D laser scan and μCT-scan to determine precisely the internal rib architecture. The main advantage of this approach is to provide a FE model which is personalised, biofidelic and taking into account both geometry and bone distribution.
