Abstract

The use of conventional glass scintillators for x-ray imaging has been limited by the need of a severe trade-off between the detection efficiency of glasses, that is low if the incoming energy exceeds about one hundred keV for conventional glasses, and the achievable spatial resolution, that is greatly affected if the thickness of the glass is increased above 2 mm. Scintillating fiber optic detectors solve this problem thanks to their light guidance properties. A set of different scintillating fiber optic plates (SFOP) has been produced to optimally detect both low (up to 50 kVp) and high (up to some hundreds kVp) energy x-rays. These detectors are coupled to a fiber optic taper which drives the light to a CCD camera through a MCP image intensifier. Alternatively, a focusing lens is employed. The detectors have been used for image acquisitions for digital radiography in the medical field (particularly at the lower energies) and for nondestructive testings, with a particular interest for the preservation of the cultural heritage.
