abstract
In recent years, X-ray micro-tomography (µCT) has become an established tool for 3D microscopy, with many applications in various fields such as geology, pharmacy, biology and many others. The technique allows researchers to visualize their sample non-destructively in 3D. The non-destructive character of µCT makes it an ideal tool for visualization and analysis of precious and rare objects, or to study the same sample under different circumstances. The resulting images show the linear attenuation coefficient in each voxel. This coefficient is influenced by both the atomic composition and density of the material in that voxel. However, due to this combined influence, no exact information on the atomic composition of the sample can be derived from the µCT data. To overcome this problem, a combination of different techniques can be used. µCT has been combined with synchrotron X-ray fluorescence (XRF) in multiple studies, amongst others to characterise a sandstone crust [1] and to study tissue-specific metal distributions in a Daphnia Magna [2]. XRF in laboratory has also been combined with µCT, amongst others to identify the different phases in an igneous rock sample in 3D [3] The disadvantage of this combination is that it requires two different measurement techniques, which can be time-consuming and pose misalignment problems. An alternative is to measure XRF radiation during the CT scan. However less accurate, it allows for a priori knowledge about the sample, facilitating the identification of the gray values visualized in the CT scan [4]. For this reason, a dedicated scanner capable of measuring XRF spectra directly associated with the µCT scan is developed at UGCT. Design features of the scanner, as well as some preliminary results are shown in this work
