Zusammenfassung:	Embodiments of radiographic imaging systems and/or methods can operate a digital radiography detector in a multiple modes, where characteristics such as an exposure integration time and dark images (e.g., number timing integration time, etc.) for first and second modes are different. The digital radiography detector can be coupled to a memory that can store a first set of one or more calibration maps for the first mode and a second set of one or more calibration maps for the second mode and a processor. In one embodiment, the processor can form a first calibration-corrected exposure image by modifying a first exposure image from the first mode using the first set of calibration maps and a second calibration-corrected exposure image by modifying a second exposure image from the second mode using the second set of calibration maps in combination with calibration maps for the first mode.
