Fig. 1. (A) Three dimensional truncated patient-specific model with an inlet length L=6D and an outlet length K=3.5d. The sac of patient-specific aneurysm model, zooming in, is marked by neck section and hemodynamic factors will be shown on sac and the neck section area. (B) An ideal model of side wall type aneurysm with an inlet length L=6D and an outlet length K=3.5d. D, diameter of inlet section; d, diameter of outlet section.
