A full-field imaging x-ray fluorescence computed microtomography system was designed for quantitative elemental analysis. An x-ray fluorescence imaging microscope combined with transmission x-ray microtomographic system was constructed at BL3C2 of the Photon Factory, KEK, Japan. The quasi-monochromatic beam produced by a double-multilayer monochromator was used as an incident beam. X-ray fluorescence images were obtained and were reconstructed by simultaneous algebraic reconstruction technique (SART) with taking into account of the self-absorption effects of the incident beam and the x-ray fluorescence of the sample. Distribution of Fe in a standard sample (1.60 mol/l FeCl2 solution in a capillary tube) was observed to evaluate the system. The density of Fe reconstructed without correction of the self-absorption effect was 9.26 % of the actual density. Using this correction method, 73.0 % of the actual density could be obtained.
