Abstract
Method of saturation management of a digital radiographic exposure image in which there are one or more saturation areas, acquired notably after a mammogram on an acquisition chain in automatic mode using a low-dose preexposure image. A mask is made from the exposure image by taking the saturation areas into account; the coverage areas corresponding to the saturation areas of the exposure image are determined on the preexposure image by using the the mask; a digital standardization processing of the gray levels of both the exposure image and the preexposure image is then carried out; and the final image is determined from a combination of the two images thus processed.
