FORTUNE — After years of testing, the U.S. Military is ready to implement a handheld device that detects brain bleeding immediately after a traumatic event, such as a vehicle accident or explosion. The Infrascanner 2000 uses infrared light to determine if a person has a brain hematoma or bleeding. Infrared light penetrates up to three centimeters into the head and detects the optical density, which is different for hematomas compared to a healthy brain. It gives a positive or negative reading in about two minutes.
