Problems solved by technology

However, the finite element method still cannot meet the needs of rapid type selection in terms of timeliness, and the virtual release technology does not consider the shortening effect before and after stent deployment, so these two methods are more used to analyze surgical plans in combination with computational fluid dynamics

Abstract

The invention relates to a stent expansion simulation display method and device after blood vessel implantation, computer equipment and a storage medium. The method comprises the following steps: 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 center line data of each point on the blood vessel center line; acquiring the model of the implanted stent, and acquiring stent parameters of the implanted stent from a stent database according to the model; and calculating according to the central line of the blood vessel, the data of each central line and the stent parameters to obtain the length of the implanted stent after being unfolded in the blood vessel and displaying the length. By adopting the method, the efficiency of calculating the length of the stent after being unfolded at each position in the blood vessel can be improved, and the unfolding form of the specified stent in the blood vessel can be quickly simulated and displayed.

Description

technical field [0001] The present application relates to the technical field of translational medicine, in particular to a stent deployment simulation display method, device, computer equipment and storage medium after being implanted in a blood vessel. 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 oc...
