An x-ray imaging system (10) includes a detector (12) that has multiple pixels, multiple data lines (50), and a common contact (62) that is at a common contact voltage potential. The readout circuit (30) is electrically coupled to the data lines (50) and has a multiple power states. A controller (36) is electrically coupled to the readout circuit (30), detects a change in operating state of the readout circuit (30), and adjusts voltage potential of the common contact (62) in response to the change in operating state.

摘要： Systems, methods and apparatus are provided through which a solid-state X-Ray detector is electronically scrubbed and a flat-field X-Ray exposure of the solid-state X-Ray detector is simulated in reference to an adjusted bias of the solid-state X-Ray detector. The simulation yields a gain image of the solid-state X-Ray detector which is in turn suitable for calibrating the solid-state X-Ray detector without projecting an X-Ray beam onto the solid-state X-Ray detector.
