Researchers develop colorized X-ray imaging for clearer material and tissue analysis

When German physicist Wilhelm Röntgen discovered X-rays in the late 1800s while experimenting with cathode ray tubes, it was a breakthrough that transformed science and medicine. So much so that the basic concept remains in use today. But a team of researchers at Sandia National Laboratories believes they've found a better way, harnessing different metals and the colors of light they emit.
