Giving rescue workers safe x-ray vision was the goal of this project to commercialize a former military "see through walls" technology. First responders can use inexpensive wireless radio transmitters to locate people inside structures before commencing a rescue operation. Look for x-ray vision systems in wide use within five years.

A smarter way to conduct search-and-rescue operations is not to blindly send in search teams or even robots, but instead to first surround the area with inexpensive wireless radio transmitters and use radio tomographic imaging (RTI) to see through the walls. Locating people moving behind solid walls before commencing a search-and-rescue operation could potentially help firefighters find victims, paramedics find elderly who have fallen, police locate illegal aliens trying to breach the border under cover of fog, and the military locate hostages inside buildings.
