摘要： A method for correcting at least one image of an object obtained with a mammography system is provided. The method comprises: acquiring a pre-exposure image of an object to determine the acquisition conditions for main images, the pre-exposure image comprising regions corresponding to the projection of radio-opaque elements, wherein a mask comprising radio-opaque elements is in an acquisition position; acquiring the main images resulting from the passing through the object of X-rays at higher doses than the dose used for acquisition of the pre-exposure image, wherein the mask comprising radio-opaque elements is in a retracted position; extracting regions from the pre-exposure image which correspond to the projection of radio-opaque elements; and determining the contribution of X-ray scatter at every point of the at least one image of the object, on the basis of the regions extracted from the pre-exposure image.
