Too many X-rays are bad for your health – that’s 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, as it requires only a small portion of 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 colleagues showed for …
