Ghost imaging constructs images of objects using information from light detected at two detectors. The idea is to use correlations in intensities between an object beam that strikes the object and a reference beam that doesn’t, similar to the use of intensity correlations from starlight to determine the diameter of a star. Now, two papers, one by Hong Yu from the Chinese Academy of Sciences, Shanghai, and colleagues and another by Daniele Pelliccia from RMIT University, Australia, and colleagues, report achieving this for the first time using synchrotron X-rays. Both use a multi-pixel detector for the reference beam and a single-pixel “bucket” detector for the object beam, but one group takes data in Fourier space and the other in real space. The work is of particular interest for medical imaging because the imaged object is subjected to a much lower dose of radiation than in conventional imaging.
