A traumatic brain injury case that diffuses axonal injury was suspected in the physician's diagnosis was simulated using finite element head model based on medical information such as MRI and CT. First, the head model matched the subject's head dimensions and material properties of the skull from the subject's age. Next, the site of the subject's head collision was estimated from the contusion, and collision velocity was estimated from the presence or absence of skull fractures and from the presence or absence of intracranial microhaemorrhage. Finally, we predicted the region of onset and severity of the neurological injury from intracerebral von Mises stress, and the analytical result showed the possibility of mild and partly moderate neurological injury. Furthermore, we assessed the effect of each parameter on the severity of the neurological injury and ascertained that collision velocity is the factor with the greatest effect on von Mises stress.
