Recent advancements in microtomography

The publications on x-ray imaging with a focus on micro- and nanotomography are becoming more and more interdisciplinary and combine the developments in instrumentation and algorithms with dedicated applications. The current challenges relate to synchrotron radiation sources of the fourth generation, to the establishment of phase contrast in laboratory-based systems, to the sound integration of machine learning into data analysis, to the dissemination of the big data, to the suitable preparation of the objects for tomographic imaging, and to the closer and closer collaboration between the experts, for example to address clinical needs for improving human health. This paper summarizes selected key aspects of the more than 60 contributions in the 15th volume on Developments in X-ray Tomography.
