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 support structure holds in place the vessels. (e) 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.
