Evaluation method of dynamic characteristics of endovascular stent based on second-order cone programming

[0046] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0047] like figure 1 As shown, the present embodiment provides a method for evaluating the dynamic characteristics of an intraluminal artery stent based on second-order cone programming, including the following steps:

[0048] Step S1: Provide a fluoroscopic X-ray imaging stereo system to acquire sequential lateral and posterior-anterior X-ray fluoroscopic images; deduce directional support filter from Mapped LS-SVM by taking horizontal and vertical directions for local directions filter, and obtain a sequence multi-scale directional support filter by filling zeros in the directional support filter. like figure 2 As shown, using Fluoroscopic roentgenographic stereophoto-grammetric analysis (FRSA) to acquire 45 frames of lateral and posterior-anterior X-ray fluoroscopy images within 1.5 seconds, respectively, the lateral and posterior-anterior X-ray f...
