X-ray multi-energy radiography with scintillator-photodiode detectors

摘要

For reconstruction of the spatial structure of many-component objects, it isproposed to use multi-radiography with detection of X-ray by combined detectorarrays using detectors of ``scintillator-photodiode'' type. A theoretical modelhas been developed of multi-energy radiography for thickness measurements ofmulti-layered systems and systems with defects. Experimental studies of thesensitivity, output signal of various inspection systems based on scintillators$ZnSe(Te)$ and $CsI(Tl)$, and object image reconstruction (with organics andnon-ogranics materials singled out) have been carried out.
