Abstract
A method of maintaining an initial bias of an x-ray detector () includes setting the initial bias of the x-ray detector. Operating state of a readout circuit () is altered. A photodiode common contact voltage potential is adjusted by a data line drift amount to approximately maintain the initial bias. An x-ray imaging system () includes a detector () that has multiple pixels, multiple data lines (), and a common contact () that is at a common contact voltage potential. The readout circuit () is electrically coupled to the data lines () and has a multiple power states. A controller () is electrically coupled to the readout circuit (), detects a change in operating state of the readout circuit (), and adjusts voltage potential of the common contact () in response to the change in operating state.
