Circle of Willis

The 3-D printed Circle of Willis (COW) provides high anatomical detail in the sub-millimeter range. Using a novel resin, RSD is able to simulate contrast-infused vasculature thereby eliminating the need to inject messy contrast through tubing that has to be constantly replaced. COW provides a much cleaner and robust solution for end users. The contrast infused COW in the angio head phantom is perfect for patient positioning training, image registration, and image quality optimization on biplane angiography and CT angio.
