概要:

A Three dimensional transparent physical model of a human head with real shape was constructed to visualize and measure relative motion between skull and brain in order to clarify the mechanism of acute subdural hematoma. The model consists of a transparent skull, brain made of silicone gel, cerebrospinal fluid to reconstruct relative motion between brain and skull, and meninges which constraints the motion. The shape was based on real-shaped three dimensional CAD … data constructed from CT/MRI images of a specific individual. The results of experiments in the cases of impactor collision to the occipital skull showed that shape of impact force pulse applied to the head was not affected on peak bridging vein stretch ratios because significant relative motion between skull and brain occurred by existence of cerebro spinal fluid. 続きを見る
