Recent developments in ultra-high field MRI have allowed researchers to explore the traveling wave regime. While traveling wave MRI is uncommon due to engineering constraints, it holds promise in a future to solve various RF transmission issues. Unfortunately, the traveling wave approach is forbidden for clinical MR systems due to their much lower field, and therefore, hard-to-fulfill cut-off requirements. We demonstrate a possible solution for the traveling wave approach at relatively low field clinical 3T system using a high dielectric insert inside an unmodified MRI. We show simulations and experimental MR images, which were generated using our propagating mode approach.
