1. A method for simulating a travel path of a catheter in a blood vessel, comprising:
obtaining, by a processor, three-dimensional imaging data of a target artery segment including an aneurysm, wherein the target artery segment refers to an artery segment which is subsequently subjected to computational catheter path simulation and includes an aneurysm;
constructing, by the processor, a three-dimensional model of the target artery segment based on the three-dimensional imaging data using computational modeling algorithms;
determining, by the processor, a preset path for the catheter to travel in a lumen of the three-dimensional model of the target artery segment based on an extending direction of an artery;
simulating, by the processor, the travel path of the catheter in the lumen of the three-dimensional model of the target artery segment;
correcting, by the processor, the travel path based on the preset path to obtain the corrected travel path; and
determining, by the processor, a shape of the catheter based on the corrected travel path;
wherein the determining, by the processor, of the preset path comprises:
determining an intervention segment between the catheter entry on the artery and the aneurysm, wherein the intervention segment refers to a catheter portion which is connected with a catheter tip portion and inserted into the artery after the catheter tip portion is inserted into the aneurysm; and
determining the preset path in the lumen of the target artery segment for the intervention segment based on the extending direction of the artery,
wherein the determining of the shape of the catheter comprises:
determining a bend angle and a bend direction of at least one bend part of the catheter along the extending direction of the catheter, wherein the bend part refers to a bend of the catheter when shaping the catheter,
manufacturing a physical catheter based on the determined bend angle and bend direction such that the catheter is designed for the patient's unique arterial anatomy.
