Abstract

Pixelated arrays of the transparent ceramic (Gd,Lu)₂O₃:Eu (GLO) scintillator for x-ray imaging have been fabricated using direct ink write (DIW) additive manufacturing followed by sintering and ceramics processing steps. These arrays consist of ~400 μm diameter pixels that are 4 mm long and have a pitch of 500 μm. When mounted on an amorphous silicon xray imaging array, pixelated GLO arrays offer >10x increase in the light output compared to black-coated monolithic GLO plates, using a 150 keV Bremsstrahlung source.
