Abstract

4D X-ray micro-computed tomography imaging (4D-¼CT) has quickly become established innumerous scientific disciplines as a driver of new insights for the study of dynamic µm-scaleprocesses. Groundbreaking insights often arise from the co-development of innovative dynamicscientific experimental setups that exploit the peculiarities of the (lab- or synchrotron-based) ¼CTsystem, their hardware and their reconstruction/analysis software. Unfortunately, conventionalparallel-beam geometries at synchrotron facilities are inefficient, placing a hardware limit onachievable spatio-temporal resolution. At the same time, the complexity of conventional frame-based4D reconstruction and analysis scales superlinearly with increasing resolution both in time and space,causing a software-imposed data bottleneck. To ensure that cutting-edge dynamic experimentalinsights can continue to improve, we propose a paradigm shift in the way we build ¼CT setups, dodynamic experimental design and reconstruct/analyse 4D data. This project will leverage the uniqueand complementary imaging development capabilities at the Sirius Synchrotron Light Source (Brazil)and the Ghent University Centre for X-ray Tomography (Belgium) to co-design new hardware andsoftware paradigms for dynamic 4D-¼CT, and to validate them on a use case regarding fluid transportduring hydrogen storage in porous rock formations (AU)
