1. A method for the processing of images in a radiological apparatus comprising: making several radiography projection images of a body; reconstructing a 3D image of the body; locating in the 3D image, structures presumed to be representative of 3D radiological signs with an associated degree of confidence, and thus presumed 3D radiological signs are obtained; determining in each projection image, a set of 2D candidate particles corresponding to projections of the presumed 3D radiological signs; assigning, by means of a fuzzy logic description, to each of the candidate particles a degree of membership in each of a 2D membership classes of a set of membership classes, each membership class being relative to a type of radiological sign, each class being preliminarily determined; considering a 2D fuzzy particle being formed by the set of the 2D candidate particles and by their respective degrees of membership in a class; making an aggregate of the 2D fuzzy particles in each projection image in order to obtain 3D fuzzy particles in a digital volume; extracting attribute information for each 3D fuzzy particle; and from the set of pieces of attribute information obtained, determining a degree of confidence for each radiological sign.
