Internal elemental microanalysis combining x-ray fluorescence, Compton and transmission tomography
Bruno Golosio,Alexandre Simionovici,Andrea Somogyi,Laurence Lemelle,Marina Chukalina,Antonio Brunetti +5 more
TL;DR: In this paper, an approach to the reconstruction problem is presented, which integrates the information from the three types of signals, i.e., Compton and Rayleigh scattering, for obtaining information on the internal elemental composition of the sample.

Metal location and thickness in a multilayered sheet by measuring Kα/Kβ, Lα/Lβ and Lα/Lγ X-ray ratios
TL;DR: In this article, a multilayered material is analyzed by means of energy-dispersive X-ray fluorescence analysis, and the results depend on the composition and thickness of the layer in which the element is situated.

Iterative Reconstruction in X-ray Fluorescence Tomography Based on Radon Inversion
TL;DR: This work describes a new approach for the inversion of the generalized attenuated radon transform in X-ray fluorescence computed tomography (XFCT), using the radon inverse as an approximation for the actual one, followed by an iterative refinement.

Cork quality estimation by using Compton tomography
Antonio Brunetti,Roberto Cesareo,Bruno Golosio,Bruno Golosio,Pietro Luciano,Alessandro Ruggero +5 more
TL;DR: A new technique based on X-ray Compton tomography is described that allows one to reconstruct and visualize the cross-section of the cork stopper analyzed, and so to put in evidence the presence of internal imperfections.
