Comparison of Positron Emission Tomography and X-ray radiography for studies of physical processes in sandstone KU Leuven Ghent University
The migration of moisture in cores of porous homogeneous sandstone of Ledian age (Belgian Eocene, Tertiary) is monitored with PET (Positron Emission Tomography) and micro-focus X-ray radiography. In the case of PET, a nuclear medical imaging technique, Co-55-EDTA (Ethylenediamine Tetraacetic acid) and R-F-18 were used as water-soluble tracers. The X-ray projection method has evolved from the better-known medical technique and allows a fast and ...
