Abstract:
1. A method of image processing in a radiological apparatus, comprising: reconstructing a 3D image of a body from a set of radiography projection images; locating structures presumed to be representative of 3D radiological signs within the 3D image; determining a set of 2D candidate particles corresponding to projections of the presumed 3D radiological signs; assigning, through a fuzzy logic description, to the 2D candidate particles a degree of membership in 2D membership classes of a set of membership classes, each membership class being relative to a type of radiological sign; 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 to obtain 3D fuzzy particles in a digital volume; and determining a degree of confidence for each 3D radiological sign from the 3D fuzzy particles.
