The handheld scanner will be used to detect intracranial bleeding on the spot, quickly identifying people who may need follow up treatment or diagnosis. The wand-like device will take advantage of near-infrared technology to determine any abnormalities in the brain's light absorption. Using an eye-safe NIR diode laser and an optical detector, the scanner will measure the light absorption of both halves of the brain. A lack of symmetry will indicate a likely hematoma caused by the...
