In recent years, X-ray detection systems for high resolution Digital Radiography (DR) and Computed Tomography (CT) have been developed at the Physics Department of the University of Bologna. The research target is the development of systems to be applied in cultural heritage conservation and industrial radiology. This report presents three systems employed successfully in the analysis of different features. The first is a micro-CT for a voxel side of around 20 microns. The second is based on an EBCCD camera that allows images to be taken with a very low photon flux and a spatial resolution of about 200 microns. The third system is based on fibre-optic bundles that transfer light to the photocathode of an EBCCD camera; the main feature of this system is high resolution (voxel side of about 15 microns), even for relatively large objects (~10 cm).

Abstract
In recent years, X-ray detection systems for high resolution Digital Radiography (DR) and Computed Tomography (CT) have been developed at the Physics Department of the University of Bologna. The research target is the development of systems to be applied in cultural heritage conservation and industrial radiology. This report presents three systems employed successfully in the analysis of different features. The first is a micro-CT for a voxel side of around 20 microns. The second is based on an EBCCD camera that allows images to be taken with a very low photon flux and a spatial resolution of about 200 microns. The third system is based on fibre-optic bundles that transfer light to the photocathode of an EBCCD camera; the main feature of this system is high resolution (voxel side of about 15 microns), even for relatively large objects (~10 cm).I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
