Claim One:
1. A method for correcting an image from a series of images acquired with an x-ray detector, said x-ray detector comprising a plurality of detector elements and each of said images being comprised of image elements respectively associated with the detector elements, each detector element emitting a series of detector signals upon being irradiated with x-ray radiation, each of said detector signals exhibiting a detector-specific temporal decay curve, said method comprising the steps of: correcting said image from said series on an image element-by-image element basis, with each image element to be corrected having been acquired during a predetermined acquisition interval and comprising respective signal contributions, to a total signal represented by the image element, from a current detector signal in said series and a plurality of preceding detector signals in said series, said current detector signal having been acquired a first time during the predetermined acquisition interval and said preceding detector signals having been respectively acquired a first time during different preceding predetermined acquisition intervals; and automatically electronically calculating said signal contributions of said preceding detector signals in said predetermined acquisition interval, to obtain calculated contributions, and subtracting said calculated contributions from the total signal represented by the image element to be corrected.
