Keywords: Interventional Devices, MR-Guided InterventionsThis study presents a technique of using high permittivity dielectric materials for catheter tracking in interventional endovascular imaging procedures. The design includes a high dielectric material cylinder at the tip of the catheter. Given the small size and limited space of the catheters, it is challenging to implement the current catheter tracking techniques. In the proposed approach, the high permittivity material mounted on tip of the catheter can amplify the local magnetic fields and makes the catheter tip visible. This method doesn’t need any feeding cables and is not sensitive to the frequency shift which makes it easy to implement.
