Researchers Develop New X-Ray Method That Reduces Radiation Dose and Improves Contrast and Resolution

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.

The main author of the paper is Irene Zanette from the European Synchrotron Radiation Facility ESRF (Grenoble, FR) and Technical University of Munich TUM (DE), and the team also comprises scientists from the Paul Scherrer Institute PSI (Villigen, CH), the Karlsruhe Institute of Technology KIT (DE), and Synchrotron SOLEIL (Gif-sur-Yvette, FR).
