Abstract

The present invention provides an analysis system and analysis method before stent implantation based on OCT. The analysis method includes the following steps: acquiring a coronary artery OCT image; converting the coronary artery OCT image into an OCT image in a polar coordinate space; detecting The upper boundary and lower boundary of the guide wire in the OCT image in polar coordinate space; the image of the upper boundary and the image of the lower boundary are fitted to obtain the inner wall contour of the blood vessel; the inner wall contour of the blood vessel is converted into a blood vessel in Cartesian coordinate space the inner wall contour of the blood vessel in the Cartesian coordinate space; acquiring the bifurcated blood vessel in the inner wall contour of the blood vessel in the Cartesian coordinate space; and displaying the inner wall contour of the blood vessel in the Cartesian coordinate space. The OCT-based analysis system and analysis method before stent implantation proposed by the present invention overcomes the problems in the prior art that it is difficult to reasonably select the size of the stent and determine the placement position of the stent, and effectively reduces the influence of the stent on the blood flow of bifurcated vessels , Improve the success rate of coronary interventional surgery.

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...
