</svg> LYSO scintillators, assembled using optical glue. Two types of backing (placed on the X-ray side of the scintillator) were used in this experiment; black cardboard on the upper left of the image and white glossy paper on the lower right. The glue joints appear brighter than the bulk of the scintillator.</table>
