Purpose Vascular flow phantoms are an invaluable tool for in vitro and in silico studies, but their design and fabrication processes are often not reported. In this study , a framework is introduced to design and fabricate 3D printable high-fidelity cohort-based averaged abdominal aortic aneurysm (AAA) phantoms. Methods AAA geometries of 50 patients were segmented from preoperative computed tomography angiography scans. The se...
