X-ray computed tomography (CT) is a fast and easy to handle non-destructive imaging technique. Derived from medical radiography, it is based on the measurement of the attenuation of X-rays by a sample rotating inbetween an X-ray source and detectors. Image reconstruction is provided through back projection algorithms. CT allows characterisation of sedimentary structures and fossils in 3D, as well as calculation of petrophysical parameters like porosity and volume. Sample size and X-ray intensity largely determine the obtained resolution, but recent technical developments allow resolutions in the submicron range.
Authors are invited to submit abstracts dealing with developments in CT hardware and software, and in interpretation of measurement results in sedimentology and palaeontology.
The session is co-sponsored by the International Association of Sedimentologists (IAS).
