An excess of X-rays is bad for your health – which is why radiographers step out of the room before they zap you. Now a ghostly physics trick could reduce the dose needed for a clear image, because it requires only a small portion of the X-rays to pass through the object being imaged.

“Ghost imaging has several benefits: reduced dose, super resolution, cheap and faster data collection,” says Andrew Kingston at the Australian National University. Ghost imaging has been demonstrated with visible light rays, but Kingston and his …
