METHOD FOR VISUALISING A PROSPECTIVE LANDING ZONE OF A VASCULAR STENT

摘要

The invention relates to a method for visualising a prospective landing zone of a vascular stent which is intended to be placed in a vessel of an organism using a delivery catheter. The method comprises the following steps: saving the parameters of the stent in an electronic data memory; capturing a first pair of two-dimensional images of a region of interest in the vessel using an image capturing unit; determining the centreline and the boundaries of the imaged vessel using a processing unit; capturing a second pair of two-dimensional images of the region of interest using the image capturing unit, once the stent has been provisionally fixed in the region of interest of the vessel without being completely disengaged from the delivery catheter; calculating a three-dimensional model of the vessel in the region of interest; calculating a three-dimensional model of the stent in its placement position for use; displaying, in a display unit, the calculated three-dimensional model of the stent or a two-dimensional projection of said model as the prospective landing zone in the image of the calculated three-dimensional model of the vessel. The invention also relates to an angiography device which is configured to carry out the method.
