Abstract
An image capture panel including a substrate with a plurality of radiation detection sensors, a plurality of conductors connected one to each radiation detection sensor, a plurality of amplifiers connected to the sensors all on the substrate, and a field electrode having an peripheral edge mounted above the radiation detection sensors and the conductors. A shielding electrode may surround the field electrode peripheral edge or may completely cover the field electrode with a dielectric layer in-between. A shielding electrode may instead surround or completely cover each amplifier. The shielding electrode may be biased to ground via a resistor, and may be constructed of a conductive paint, such as silver paint.
