1. A method implemented by an imaging system comprising an imaging device and a calculation device comprising a calculation unit, the imaging device being connected to the calculation device, wherein the method comprises:
a capture, by the imaging device, of a 2D image of a vascular structure and of an endoprosthesis comprising a plurality of stents, by X-ray;
an acquisition, by the calculation unit, of a 3D model of the vascular structure;
an acquisition, by the calculation unit, of a model of an endoprosthesis in the vascular structure;
a determination, by the calculation unit, from the 2D image, and for each stent, of values comprising at least one position, an angle of intrinsic rotation (rx′), and at least one deployment value;
a simulation, by the calculation unit, of a deployment in the 3D model of the vascular structure, for each stent, of a model of the stent representing a structure of the stent, from the values determined in the determination step, said model of the stent being initialized on a basis of the model of the endoprosthesis; and
a display, by the calculation device, of the stent models deployed in the simulation step, on one or more display screens; and
said method being wherein the determination, by the calculation unit, for at least one stent, of its angle of intrinsic rotation (rx′) comprises the determination of the angle of intrinsic rotation (rx′) for which at least one 3D position projection of at least one radiopaque marker on the stent most closely matches to at least one image of the at least one marker on the 2D image.
