Abstract
A front side illuminated photo detector array is shielded from X-ray cross-talk by filling the septa between individual photo detector diodes with a high atomic number material such as tungsten. The processing circuitry is also shielded from stray X-rays by a barrier such as tungsten placed between each photo detector diode and the processing circuitry. This barrier serves a dual role as shielding the processing circuitry from stray X-ray radiation and acting as the electrical contact between the detector diode and the circuitry.
