Abstract
Method and apparatus and computer programs and computer medium for improving quality of a radiographic image of an object obtained by an X-ray apparatus containing an antidiffusion grid, placed between the object and a receiver of radiographic images, The grid is displaced in rectilinear translation in its plane on pickup of the image, between two positions according to a time displacement law which is a continuous curve with a time precision of approximately ±10% presenting at least five separate parts, the displacement taking place at constant speed over at least two parts and at variable speed over at least one part.
