Cross-Sectional Geometry and Mass Density Distributions of Humans and Laboratory Animals

摘要

The purpose of this study was to determine the cross-sectional geometry and mass density distribution of a ten-week-old Texas Duroc female porcine subject using the x-ray computerized tomographical (CT) method and to perform a comparative study of anatomical features of this subject and a three-year-old female child specimen. The comparisons were made on the location of the center of gravity and the inertia tensor in the head, neck, head and neck, and cervical spine regions. Some immediate applications of this data are inputs to finite element models, lumped parameter biodynamic models, computer simulation of vehicle crash victims, and dummy design.
