Abstract
Method and apparatus for a radiographic image of an object obtained by a radiography apparatus containing an X-ray emitter, in which an anti-scatter grid placed between the object and a radiographic image receiver is displaced, on rectilinear translation in its plane, when acquiring the images, between a starting position and an arrival position, according to a time displacement law of reference, at a greater rate of displacement in proximity to a starting position and to the arrival position. A measurement of the energy received in the form of X-radiation by the receiver is used to modify the rate of displacement of the grid at every instant.
