Abstract

The invention provides a stent-implantation pre-operation analysis system and method based on OCT. The analysis method includes the following steps: acquiring coronary-artery OCT images; converting the coronary-artery OCT images into polar-coordinate-space OCT images; detecting upper borders and lower borders of guide wires in the polar-coordinate-space OCT images; matching upper-border images and lower-border images to obtain vessel inner-wall outlines; converting the vessel inner-wall outlines into Cartesian-coordinate-space vessel inner-wall outlines; obtaining bifurcate vessels in the Cartesian-coordinate-space vessel inner-wall outlines; displaying the Cartesian-coordinate-space vessel inner-wall outlines. According to the stent-implantation pre-operation analysis system and method based on the OCT, the problems are overcome that in the prior art, it is difficult to reasonably select stent sizes and determine stent placement locations; the influences of stents on bifurcate-vessel bloodstreams, and the success rate of coronary-artery interventional treatment operations is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an OCT-based analysis system and analysis method before stent implantation. Background technique [0002] Coronary artery disease (CAD) is the leading cause of death worldwide. At present, percutaneous coronary intervention is generally used in the treatment of coronary heart disease, that is, the stent is guided to the narrow part of the blood vessel, and then the stent is stretched by pressurizing the balloon, so as to expand the lumen of the vessel and improve the blood flow capacity. Before stent implantation, accurate measurement of the lumen is very important, which determines the selection of stent size and the optimal position of stent placement. Improper stent size may lead to malapposition of the stent, eventually leading to acute stent thrombosis and late restenosis. Especially, for the new generation of bioresorbable vascular scaffold (BVS), due to its limit...
