Flow chart of images describing the manufacturing process for a patient specific phantom of the Circle of Willis. a An Angio CT image is acquired of the neurovasculature. b The neurovasculature is segmented out from the rest of the brain tissue and a 3D geometry is created. c A 3D mesh of triangular vertices is created within Autodesk Meshmixer. d The mesh is made a solid geometry and hollowed out for the creation of vessel lumens and a (e) support structure holds in place the vessels. Arrow pointing to hardened support material to reduce vessel sagging. f The model is 3D printed in Stratasys Tango+ material to simulate the vascular compliance and is ready to be connected to a flow loop for simulation studies
