Potential for improved object reconstruction accuracy.

Abstract

For reconstruction of the spatial structure and thicknesses of complex objects and materials, it is proposed to use multi-radiography with detection of X-ray or gamma-radiation by combined detector arrays of scintillator-photodiode type. Experimental studies have been carried out of the energy dependence of sensitivity of dual-energy inspection systems based on scintillators $ZnSe(Te)$ and $CsI(Tl)$.
