Patent ID: 8894280

Claim:
A digital radiography system comprising: a digital radiography detector adapted to operate in a first mode to capture an first exposure image using a first exposure period and a first set of one or more dark images associated with the first exposure image; the digital radiography detector adapted to operate in a second mode to capture a second exposure image using a second exposure period and a second set of one or more dark images associated with the second exposure image; a memory coupled to the digital radiography detector to 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; a computing processor to form a first calibration-corrected exposure image by modifying the first exposure image using the first set of calibration maps and to form a second calibration-corrected exposure image by modifying the second exposure image using the second set of calibration maps in combination with calibration maps for the first mode.
