How ORS Visual Was Used

The luminal domain was extracted from the anatomy, and subsequently considered as a realistic ‘tortuous’ AAA geometry. For this purpose, the medical imaging software ORS (Object Research Systems, Montréal, QC, Canada) was used. Fig. 1. Detail of the patient-specific geometry (PSG-1) showing (a) initial facets, (b) single surface and (c) 3D centrelines.
