Abstract

In a method for correction of an image in a series of images acquired with an x-ray detector; wherein the x-ray detector is composed of a number of detector elements and an acquired image is composed of image elements associated with the detector elements, a series of detector signals is generated in a detector element by x-ray radiation, the detector signals respectively exhibiting a detector-specific temporal decay curve; and an image element to be corrected and acquired over a predetermined acquisition interval contains signal portions of the current and preceding detector signals acquired during this acquisition interval. By calculating signal portions of preceding detector signals acquired in the acquisition interval and subtracting them from the image element to be corrected, the image quality of an image from a series of images acquired with a digital image acquisition apparatus is improved.
