3D Printing of the Cerebral Vasculature Exceptionally using Freeware: A Quick and Easy Guide Technical Note

Alexander Küffer, Luca Regli

High-resolution 3D reconstructions of the cerebral vasculature are essential for preoperative planning of complex interventions in vascular neurosurgery. Quick-segmentation algorithms provided by expensive radiology applications often result in unsatisfactory 3D reconstructions. Here we show how to quickly segment and print a detailed 3D model of the cerebral vasculature without extensive knowledge in 3D modeling. Exceptionally using freeware, the total costs for the generation of a real size model of the circle of Willis are less than $10. The 3D models will be particularly valuable during preoperative planning and for patient information.
