| 摘要 |
Embodiments of the invention provide a radiation detector comprising a pixel element, the pixel element comprising: a first diode element having a node capacitance associated therewith, the element being operable to pass electrical charge therethrough between terminals thereof in response to incident radiation; and an auxiliary charge storage reservoir, wherein the detector is operable by means of charge transfer between the auxiliary charge storage reservoir and a first terminal of the first diode element to reduce a rate at which an electrical potential VX of the first terminal changes in response to a cumulative amount of incident radiation. |
