1. 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, the method comprising: creating a 3D map of suspicion with a detection computer from the previously acquired medical images, wherein the 3D map of suspicion comprises a 3D matrix of voxels whose values indicate a degree of suspicion that shows whether the corresponding regions of the tissue matrix are suspect; generating a 2D map of suspicion with an implementing computer 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, wherein the 2D map of suspicion comprises a 2D matrix of pixels whose values indicate a degree of suspicion that is determined from the corresponding degree of suspicion from the 3D map of suspicion; and generating a final 2D image of the tissue matrix with the implementing computer from the first image and/or from the 2D map of suspicion, wherein the final 2D image highlights suspect regions in the tissue matrix.
