Biofidelic Model of Human Cranium and Intracranial Contents

INTRODUCTION

Brain injury researchers and human protection engineers need a tool to investigate how mechanical loading influences brain motion, strain and displacement. A new test object must be able to quantify metrics of soft-tissue/brain tissue disruption from head injury. Current testing for head injury is crash test dummies. This model determines the bulk head response (whole head displacement, linear and angular acceleration) to impacts. The problem with this model is that it does not provide any insight into brain response to more complex loads, such as blast.

DESCRIPTION OF TECHNOLOGY

This invention is an advanced human head model which not only models the bulk motion of the human head during impact but also the intracranial contents of the human head with the ability to visually track brain deformation during impact. These models of intracranial contents are matched in material character to that of human brain tissue and are of similar geometry of actual human brains. This invention will enable users to not only quantify head motion/acceleration in injury but brain motion and strain in testing and developing protection against more complex injuries than motor vehicle accidents.
