Abstract
An apparatus and method for detecting an electrostatic charge on a flat panel imager pixel array. In one embodiment, the apparatus includes an insulator layer and a flat panel pixel array coupled to a bottom surface of the insulator layer. Each pixel of the pixel array has a storage capacitance, and an electrostatic charge corresponding to a voltage applied through an electrode coupled to a top surface of the insulating layer may be detected from each storage capacitance.
