    摘要: A method of processing a radiological image of an organ. The method may comprise generating a recombined image (R) from at least one previously acquired low energy image (L) and one high energy image (H) of a portion of the organ. The recombined image comprises a background and one or more areas corresponding to the presence of a contrast medium in the organ. The method may further comprise correcting the recombined image (R) by compensating (C) for the nonuniformities present in the background to obtain a compensated recombined image in which the background has a substantially uniform grey level.

    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.

    摘要: A processing method for images obtained by tomosynthesis comprising acquisition of a plurality of 2D projection images of a region of interest of a patient; reconstruction of a 3D digital image from the acquired 2D projection images. An embodiment of the method is characterised in that it comprises: detection of an object in the reconstructed image; estimation of a thickness limit characteristic of a contrast default of the voxels for a diameter of the object; estimation of the thickness of the object; comparison of the thickness of the object to the thickness limit; and in that if the thickness of the object is less than the thickness limit, the method further comprises application at least to the voxels of the object in the reconstructed image of a multiplicative corrective factor equal to the ratio between the thickness limit and the thickness of the object.
