Comparison of CsI:Tl and Gd₂O₂S:Tb indirect flat panel detector x‐ray imaging performance in front‐ and back‐irradiation geometries

Abstract

Back irradiation may improve the inherent x-ray imaging performance of I-FPDs composed with CsI:Tl and GOS scintillators. This approach can be leveraged to improve tradeoffs between detector dose efficiency, spatial resolution and noise for higher energy x-ray imaging.
