High Yield Complementary Metal-Oxide Semiconductor X-ray Detector

摘要

A digital X-ray detector includes a scintillator that is configured to absorb radiation emitted from an X-ray radiation source and to emit light photons in response to the absorbed radiation. The detector also includes a complementary metal-oxide-semiconductor (CMOS) light imager that is configured to absorb the light photons emitted by the scintillator. The CMOS light imager includes a first surface and a second surface. The first surface is disposed opposite the second surface. The scintillator contacts the first surface of the CMOS light imager. The CMOS light imager further includes a CMOS pixel array with an array of CMOS pixels. Each individual CMOS pixel includes at least two row select transistors.
