Abstract

In this study, experimental results on the signal dispersion of a gas detector volume of a multimedia imaging detector, operating on both gaseous and solid-state ionization principles, with specific emphasis on single X-ray exposure dual-energy radiography, are presented. The results of this study indicate that the gas detector volume of the multimedia detector technology exhibits excellent signal characteristics suitable for a large number of imaging applications. By focusing on the gas detector element, drift distance causes significant effects on both the amplitude and full-width at half maximum due to mobility dispersion and space-charge. An improved signal results with increasing gas pressure.
