Evolution of Micro-CT
Figure 8: Virtual cross sections at 4 different time points (0, 10, 20, 40 minutes) for the volume of interest (VOI) scan. All three phases are clearly distinguishable at 4.5 μm voxel resolution and 60 seconds per rotation.
higher resolution imaging in the form of virtual cross sections through the sample at different time points. Te lightest phase is the fused silica, the intermediate phase is the brine, and the darkest phase is the oil. Although a bit slower, clear infiltration of the oil into the brine-saturated network can be seen.
Summary Micro-CT has become a more commonplace technique
over the past decade, providing invaluable non-destructive 3D information for a variety of research and industrial applica- tions. With the advent of higher-powered sources and faster detectors, coupled with specialized soſtware and application experience, lab-based micro-CT is now pushing into a new realm of temporal resolution, allowing for true dynamic CT experiments. Te future of micro-CT is vast and virtually unlimited, and it’s certainly an exciting time to be a part of these developments. Te possibility to scan and analyze fast dynamic experiments opens doors for many other more in- depth studies.
