Abstract
A scintillator pack comprises an array of scintillator pixels and an x-ray absorbing layer disposed in inter-scintillator regions between the scintillator pixels. The x-ray absorbing layer acts to absorb x-rays and protect underlying regions of the inter-scintillator regions. The x-ray absorbing layer may be formed by a number of methods including casting and melt infiltration.
