    摘要： A method to generate a final image with a medical imaging system, wherein the final image highlights suspect regions in a tissue matrix and wherein the final image is generated from a first image and from previously acquired images of the tissue matrix is provided. The method comprises: creating a 3D map of suspicion from the previously acquired medical images; generating a 2D map of suspicion by projecting all or part of the 3D map of suspicion onto a plane from a point reproducing the conditions of acquisition of the first image; and generating a final 2D image of the tissue matrix from the first image and/or from the 2D map of suspicion, wherein the final 2D image highlights suspect regions in the tissue matrix.

    摘要： In a method for the 3D viewing of tomosynthesis images in mammography, an algorithm is proposed for the viewing of radiology signs in series of 3D data. When the digital volume is being viewed by a practitioner, the disclosed algorithm is used to provide a dynamic indication of the position of the radiology signs on the 3D image by means of markers. The use of dynamic viewing draws the practitioner's attention to the zones of clinical interest. The disclosed algorithm thus highlights all the radiology signs in the 3D image of the breast.

    摘要： In a method for the processing of radiological images for the detection of opacities in a radiography image, an algorithm is proposed for detecting opacities according to their contrasts. To determine a contrast that is not over-estimated in each element, an algorithm is proposed for computing the background intensity by means of a sliding-window filtering. This type of sliding-window filtering computes the set of mean values of grey levels about an immediate environment of a region of elements whose size depends on the size of the opacity to be detected. The algorithm considers a background intensity of the region of elements to be the lowest mean value grey levels among the set of mean values of grey levels.
