Abstract
The X-ray fluorescence microtomography method is presented, which is capabl e of virtually slicing samples to obtain cross-sections of their inner stru cture. High precision experimental results of fluo-tomography in "pencil-be am" geometry with up to 1.2 mum resolution are described. Image reconstruct ions are based on either a simplified algebraic reconstruction method (ART) or the filtered back-projection method (FBP). Phantoms of inhomogenous tes t objects as well as biological samples are successfully analyzed. (C) 2001 Elsevier Science B.V. All rights reserved.
