Abstract:
1. An x-ray detector assembly comprising: a plurality of x-ray scintillator elements arranged in an array; a first silicon substrate having a top surface and a bottom surface; a front-illuminated array of photodetectors disposed on the top surface of the first silicon substrate and having coplanar contacts, the array of photodetectors aligned so as to match the array of x-ray scintillator elements; a second silicon substrate fused to the bottom surface of the first silicon substrate, the second silicon substrate providing on its distal side a planar connectivity pattern matched to electronics in a signal acquisition system; and one or more through-hole connections that traverse both silicon substrates so as to connect the top surface of the first silicon substrate to said distal side of the second silicon substrate, the through-hole connections configured to couple the contacts of the photodetectors from the top surface of the first silicon substrate to the connectivity pattern on the distal side of the second silicon substrate.
