    Abstract
  • In order to find a simple method to build the coronary artery stenosis model based on medical images, a simplified narrow coronary artery-stent coupling finite element (FE) model based on CT images was built using the feature contour extraction method. The mechanical properties of the stent in an ideal coronary artery stenosis was then studied using the CT-based FE model in comparison with the ideal simplified artery FE model. In addition, some clinical study results were used to verify the rationality of the two models. The results show that some differences in mechanical properties existed between the two models, such as the stress distribution, expansion stiffness, recoil rate, dog bone rate, and the mean area of blood vessel. For the CT-based model, the mean stress of vessel was 1.22 MPa and the minimal area of vessel after stent implantation was 6.1 mm2, while they were 1.54 MPa and 5.1 mm2, respectively, in the ideal simplified model. The results obtained by the CT-based simplified model was more close to the clinical results than the ideal simplified model.
