Abstract
The invention relates to a two steps image capture panel for recording x-ray image information. More particularly, the invention relates to a method and an apparatus for directing the internal electric field to capture the x-ray image first on an insulating surface, avoiding charge injection noise from the insulating surface, and then re-directing the internal electrical field to transfer the image charge from the insulating surface to a conductive readout electrode with electric field sufficient for charge gain during image readout.
