Abstract
For the sake of emergency treatment for head injury, and even for applying the appropriate treatment for the patient, to estimate the damage properly has been required. The objective of this study is prediction simulation and visualization of the types of brain injury in head trauma accidents. In this paper, the case of contrecoup contusion of a woman on a bicycle who was contacted by a walker and hit her left side head on the asphalt road was simulated using multibody body dynamics and finite element (1%) methods. The contusion shown on the medical images were compared to the pressure pattern in the FE model and the site and severity of neurological damage were evaluated from von Mises stress. As the result, the prediction simulation matched well the site of brain contusion, and the severity of the predicted neurological injury was consistent with the physician's diagnostic result.
