China team brings X-ray vision to life with a compact high-speed ghost video cam

Chinese scientists have developed a new tabletop X-ray ghost imaging method that allows them to capture real-time “see-through” video of fast-moving objects. The team’s system could be used to capture dynamic objects such as rotating aircraft engines or biological movements like a beating heart. Importantly, this could all be accomplished with a lower radiation dose and simpler set-up than traditional X-ray methods. “In contrast to other available X-ray imaging techniques for moving objects, our...
