Abstract
A technique for compensating for a retained image includes sampling image data from a digital detector following termination of a first exposure to model decay of the retained image. Based upon the modeled decay, further decay of the retained image is predicted. The predicted decay values are employed to correct or compensate for the decaying retained image in a subsequent exposure. The technique is particularly well suited to compensation of retained images in fluoroscopic exposures following radiographic exposures in a digital x-ray system.
