Artificial cerebrovascular replicas present realistic vascular geometry and have versatile applications in the development and testing of medical devices. Different methods for construction of patient specific silicone vascular models have been proposed previously; however, due to the variations in the cerebrovascular anatomy, results obtained from these models may not be generalized to the entire population. To prepare a geometrically standard model, vessel characterization is necessary. Common attributes measured to quantitatively describe blood vessels include diameter, length, branch angle, and tortuosity, and among them, tortuosity evaluation is widely discussed. To date, tortuosity lacks a universal definition, but is generally used to summarize curvature information along the centerline of a blood vessel.
