Abstract

A method for reducing lag artifacts in digital radiographs is provided in combination with an X-ray source, an X-ray detector, and a positioning station for a target to be imaged, said station being interposed in the opening cone of the radiation emitted by said source between said source and said detector, and said method comprising the combination of the following steps:a) acquiring a sequence of frames of radiographic images of a target, each of said images being acquired by means of imaging exposures of said target performed at different consecutive time instants and at a predetermined time interval between said time instants;b) said images of said sequence reproducing zones or areas of said target that overlap at least partially with each other with reference to two consecutive images of said sequence of images;c) registering the images of said sequence of images based on the image data of said overlapping zones;d) combining by merging said registered images, generating a single image comprising the reproduction of the zones of the target acquired from said images of the sequence of images.
