Hybrid Active Matrix Flat Panel Imager
A hybrid x-ray detector that absorbs incident rays directly and indirectly, and the photoconductor can sense both x-rays and optical photons Background: X-ray detectors currently commercially available consist of direct and indirect detectors. Direct detectors take x-ray inputs and are directly converted to electron hole pairs and digitized...

Fabrication Method for Fused Multi-layer Amorphous Selenium Sensor
This novel technology uses blocking layers to dampen electronic noise and the effect on imaging, for improved optical and x-ray sensing Background: Amorphous selenium (a-Se) has been commercialized both as an optical sensor and direct x-ray detector, and a-Se with avalanche gain has also been proposed for use in an indirect x-ray detector. Advantages...
