摘要: Described herein is a method of radiographic imaging providing low access time prior to the start user-requested X-ray exposure, while at same reducing or eliminating artifacts associated with short times. The includes steps exposing detector for period t e ; reading obtain an exposure reading; offset reading, wherein obtained after w greater than and subtracting from reading. Where subjected readings lasting periods r taking are also taken during . After final , then preferably equal As result, approximately sampling scheme used both (i.e., operating conditions imposed on reading), thereby more accurate less image when subtracted
