Description
Today's industrial X-ray micro computed tomography (µCT) specimen systems allow high resolution 3-D examination of samples in biology or materials science. Up to now, X-ray absorption contrast imaging has been the standard contrast mechanism in these systems. Recent developments showed that phase contrast imaging can lead to significant contrast enhancements [1]. In the past few years, grating interferometry has established itself as a suitable technique for differential phase contrast (DPC) imaging on conventional X-ray tubes [2].
We have developed a new imaging setup based on a grating interferometer and a microfocus X-ray tube. With a uniquely short setup length of 32cm, the setup geometry has been designed for an immediate integration into a commercial SCANCO Medical µCT 100 scanner. As opposed to conventionally used planar shaped gratings, cylindrically bent gratings are used, resolving the problem of a limited field of view [3]. Here we present the first imaging results on the µCT scanner.
