As materials and components are becoming increasingly complex, 3D imaging techniques allowing for probing samples on different length scales are rapidly gaining importance. Recent developments in tomography using novel X-ray tubes as well as X-ray optics have pushed the reachable spatial resolution to values that previously required synchrotron radiation. Synchrotron light sources are nowadays boosting X-ray tomography up to nano-resolution, combined with novel contrast schemes which allow for correlating the morphology inside a sample with the distribution of chemical species, grain orientation or crystalline phases. Furthermore, the reachable spatio-temporal resolution permits following the evolution of a specimen in 3D by time-resolved tomography. On the other side, neutron tomography has been developed further and now enables us to exploit the specific contrast mechanisms associated with neutrons, including magnetic and nuclear interactions. The aim of the symposium is to provide information on the rapidly developing experimental techniques with respect to novel potential applications. Tomography using different radiation sources for materials science, applied physics and various areas of engineering will be presented. As 3D tomography heavily relies on a mathematical foundation, namely the process of data reconstruction and algorithms allowing us to extract information from images, a further focus is put on volume data processing and analysis.
