Thuering, T.Modregger, P.Grund, T.Kenntner, J.David, C.Stampanoni, M.2013-04-252013-04-252013-04-25201110.1063/1.3618672https://infoscience.epfl.ch/handle/20.500.14299/91787X-ray grating interferometry is a well established technique to perform differential phase contrast imaging on conventional x-ray tubes. So far, the application of this technique in commercial micro computed tomography scanners has remained a major challenge due to the compact setup geometry. In this letter, we report on the design of a compact imaging setup using a microfocus source. Due to the extreme wave front curvature, the gratings are fabricated on a flexible substrate, enabling precise cylindrical shaping. A laboratory setup and a modified SCANCO μCT100 scanner have been built, allowing high resolution and large field of view imaging. © 2011 American Institute of Physics.CIBM-PCtext::journal::journal article::research article
