UV Exposed Optical Fibers with Frequency Domain Reflectometry for Devi…

Shape tracking of medical devices utilizing strain sensing properties in optical fibers has seen elevated consideration in recent years. On this paper, ItagPro we suggest a novel steerage system for intra-arterial procedures using a distributed pressure sensing machine based on optical frequency domain reflectometry (OFDR) to track the shape of a catheter. Tracking enhancement is provided by exposing a fiber triplet to a focused ultraviolet beam, iTagPro smart device producing excessive scattering properties. Contrary to typical quasi-distributed strain sensors, we suggest a actually distributed strain sensing strategy, which allows to reconstruct a fiber triplet in actual-time. A 3D roadmap of the hepatic anatomy built-in with a 4D MR imaging sequence allows to navigate the catheter inside the pre-interventional anatomy, and iTagPro locator map the blood flow velocities within the arterial tree. We employed Riemannian anisotropic heat kernels to map the sensed knowledge to the pre-interventional mannequin. Experiments in artificial phantoms and an in
