Abstract

In this study, experimental results on the signal dispersion of a multimedia imaging detector, operating on gaseous 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 multimedia detector technology exhibits excellent signal characteristics suitable for a large number of imaging applications. On the other hand, drift distance causes significant effect on both the amplitude and full-width at half maximum (FWHM) due to mobility dispersion and space-charge. An improved signal results with increasing gas pressure.
