Abstract:
A method for a radiographic imaging of an object by a radiography apparatus having means for providing an X-ray emitter; an anti-scatter grid placed between the object and means for providing a radiographic image receiver, comprising:displacing the grid in rectilinear translation of the plane of the grid when acquiring the images, between a starting position and an arrival position, according to a predefined time displacement law; the displacement being at a rate to cause the grid to translate at a greater rate of displacement in proximity to the starting position and to the arrival position than between those two positions; and measuring the energy received in the form of X-rays by the receiver to modify the rate of displacement of the grid at every instant wherein the displacement of the grid is adjusted to the energy received by the means for providing a radiographic image receiver so that, during exposure time each part of the means for providing a radiographic image receiver has been exposed to substantially the same quantity of radiation energy.
