Abstract
Finite-element models of human body were introduced in the early 90's for passive safety systems designing. Performing geometrical personalization of such models is of primary interest for optimizing their biofidelity. Then, the purpose of this study was to bring a deeper insight on external and internal human body geometry, and to provide tools for personalized modeling. A geometrical database containing both external (full body anthropometry) and internal (morphometry of the spine, pelvis and rib cage) data measured on 85 volunteers was obtained thanks to classical anthropometrical measurements and using stereoradiographic 3D reconstructions methods. This database analysis yielded to a detailed description of both external and internal body geometry for healthy european subjects. It resulted also in the development and validation of a statistical method to estimate anthropometrical (external) and morphometrical (internal) parameters from about 200 external/external and external/internal anthropometrical relationships (simple or multiple linear models). Thanks to this method only 10 anthropometrical measurements may be used for the modeling of external (43 dimensions) and internal (155 dimensions) human body geometry (mean error: 2.3%(2σ :14.2%) ). At last, this study has brought a contribution to the stereoradiographic 3D reconstruction of the rib cage in order to obtain a geometrical personalization of the trunk bones(spine, pelvis, and rib cage) from frontal and lateral X-rays. The anthropometrical and morphometrical data collected and the tool for geometrical modeling developed still offer numerous possibilities in impact and comfort biomechanics and for clinical applications.
