Schematic representation of the stepwise workflow for generating high-fidelity three-dimensional surface models from 3D rotational angiography datasets. The reconstruction was performed using the inhouse software MERCIA within MeVisLab©, followed by manual refinement in Blender to remove artifacts, adjust inlets and outlets, and smooth the mesh. The vascular centerline was extracted using the Vascular Modeling Toolkit (VMTK), and further processing in MATLAB enabled semi-automatic detection of the aneurysm neck curve.
