writes "If you've ever been in a serious car accident, you've probably had a CT scan to give doctors a clearer idea of your injuries. Soon, your car might get a CT scan, too. Scientists at the Fraunhofer Institute have developed a giant new CT scanner (dubbed, yes, XXL CT) that can scan very large objects, like cars. But why? Turns out a CT scan of a post-crash vehicle offers an unprecedented precision look at the internal damage details, without disturbing the wreckage further. A crashed car is hoisted onto a turntable, and as it turns, two X-ray detectors on either side scan it. Then multiple images are merged into a single, three-dimensional CT scan. The scanner also can handle airplane wings and shipping containers, which means there may be possible anti-terrorism uses in the future."
