Modeling of Human Thorax

Most of the automotive companies use computer models to simulate full scale crash tests before launching a real experiment. A vast effort was put into the development of crash dummy models for crash simulations. In any event, a safe vehicle should be designed for human, not for dummies.

With today's high speed computers, we believe that the time for a human model has come. The THORAX model we developed is part of the effort in making a complete human model available for the auto industry. This model represents a 50th percentile male in a sitting position. It consists of detail modeling of bones (ribs, vertebrae), costal cartilage, sternum, organs (heart, lung), vessels (aorta, pulmonary vein, etc.), diaphragm, and various muscles.

Figures shown below are deformed shapes of the rib cage and the heart, diaphragm, and attached blood vessels.
