摘要：

An X-ray transmission microtomography (CT) system combined with an X-ray fluorescence microtomography (XRF mu CT) system was implemented in the Brazilian Synchrotron Light Laboratory (LNLS), in order to determine the elemental distribution in prostate samples aiming at establishing a correlation between the concentration of some elements and the characteristics and pathology of the tissues. The CT images were reconstructed using a filtered-back projection algorithm and the XRF mu CT images were reconstructed using a filtered-back projection algorithm with absorption corrections.
