Radar Tracks Brain Injuries

Engineers at Georgia Tech have designed a radar device that may help health care providers find incidents of traumatic brain injury faster and more easily than ever before.

By using a specially designed radar gun, researchers can analyse subtle differences in a person’s gait to determine whether or not that person has sustained a concussion.

As a person walks toward and then away from the machine, the radar gun throws out microwave signals that hit the body and bounce back.

How these signals reflect tells the computer both how fast the person is moving and in what direction. The computer can then look at the movements of the torso, feet and arms separately.

The engineers first looked at how people walk when they are wearing goggles to simulate drunkenness—a rough estimate of what it’s like to have a concussion. They found that people walk differently when wearing the goggles than they do without them, exhibiting aberrations that the radar system can detect. Next the individuals were asked to do the same task while reciting the months of the year in reverse. With this, the trend intensified.

Although the system collects very technical information, it reads out in a simple way.

If the system were scaled down enough, coaches and soldiers could carry it right onto the field of play or the field of battle, where concussions happen the most, allowing them to diagnose brain trauma as soon as it happens.
