A new method of X-ray imaging that reduces the radiation dose per scan and at the same time drastically improves the computed tomography (CT) has been developed by a group of European researchers.
The new method is based on the combination of the high contrast obtained by an X-ray technique known as grating interferometry with the three-dimensional capabilities of CT. It is also compatible with clinical CT apparatus, where an X-ray source and detector rotate continuously around the patient during the scan. The results are published in Proceedings of the National Academy of Sciences (PNAS) dated 4-8 June 2012.
