It's sadly ironic that the very properties which make our skulls such excellent brain protectors, strength and rigidity, often work against us after head injuries. Not only does the hard bone conceal damage from concussions and bleeding, say, but it also confines the swelling, causing intra-cranial pressure to surge, a situation that can lead to further brain damage. While CT scans and magnetic resonance imaging systems are crucial to an accurate assessment, they are rarely available to emergency medical personnel at remote accident sites or on the battlefield. To help address the need for rapid and timely diagnosis of head traumas, separate research teams at the U.S. National Institutes of Health (NIH) and the Office of Naval Research (ONR) have each developed hand-held devices that use Near Infra-Red (NIR) imaging to quickly detect hematomas (internal bleeding) and other life-threatening traumatic brain injury (TBI).
