In case where self-absorption of the sample is low, e.g. low-absorbing biological samples, Full Field –XRF (FF-XRF) projections can be recorded for various orientations of the sample. This allows to reconstruct a 3D image from the two dimensional FF-XRF images, the so-called µCT technique.

As a matter of course, due to the capability of the CXC to record energy dispersive images with the full spectroscopic information stored for every pixel of the images, the generation of various element-specific 3D sinograms from one µCT data set is possible. Combining the CXC with a magnifying polycapillary enhances the spatial resolution beyond the physical pixel size of the pnCCD [De Samber (2019)].
