Method and system for processing vascular radiography images which have been
reconstructed by three-dimensional modelling, in which: from this three-dimensional
modelling there is determined a three-dimensional model known as the masked model
which features the calcified elements and the prosthetic elements, but not the
vascular elements; a three-dimensional model known as the subtracted model, which
features the vascular elements alone, is determined; these two models are merged,
weighting their voxels so as to increase the contrast between the images of the
masked model and the images of the subtracted model; and summing the voxels thus weighted.
