Abstract

The invention relates to a stent model matching method and device for intracranial aneurysm and a stent simulation display method. The stent model matching method comprises the following steps of: acquiring image data related to intracranial artery blood vessels, and constructing a three-dimensional blood vessel model by processing the image data; obtaining a target area in the three-dimensional blood vessel model, and extracting a blood vessel center line in the target area and a plurality of pieces of center line data of points on the blood vessel center line; carrying out processing according to the blood vessel center line and the center line data to obtain a nominal diameter and a nominal length of the stent; and according to the nominal diameter and the nominal length of the stent, obtaining a matched stent model in a preset stent database. By adopting the method, the stent model matching efficiency and the blood vessel suitability can be improved.

Description

technical field [0001] The present application relates to the technical field of translational medicine, in particular to a stent model matching method and device for intracranial aneurysms, and a stent simulation display method. Background technique [0002] Intracranial aneurysm refers to an abnormal bulge that occurs on the wall of an intracranial artery. It is the first cause of subarachnoid hemorrhage and threatens the lives of about 5% of the world's population. [0003] The early treatment of intracranial aneurysms was mainly surgical aneurysm clipping, which greatly increased the risk of surgery due to the need for craniotomy. Currently the most important method for intracranial aneurysms is coil embolization. The main principle is to release a limited number of soft metal coils into the aneurysm cavity to change the blood flow in the aneurysm cavity, thereby triggering the gradual formation of thrombus in the aneurysm cavity, and finally occluding the aneurysm. Fo...
