Claim Text:
1. A radiation detector comprising: a scintillator layer configured to convert incident radiation into lower energy optical photons, wherein the scintillator layer comprises a plurality of pixels formed by one or more dividers, and wherein the one or more dividers form one or more radiation pathways through the scintillator layer; a photodetector layer configured to detect the lower energy photons generated by the plurality of pixels within the scintillator layer; signal electronics configured to receive signals generated by the photodetector layer; and one or more barrier layers disposed between the photodetector layer and the signal electronics, wherein each barrier layer of the one or more barrier layers comprises electrically conductive vias containing a high Z material positioned to block high energy radiation that passes through the one or more radiation pathways from reaching the signal electronics, wherein the vias are arranged within the electrical substrate to substantially align with the one or more radiation pathways of the scintillator layer.
