Recent developments in ultra-high field MRI have allowed researchers to explore the traveling wave regime. Traveling wave MRI holds promise in a future to solve various RF transmission issues, however, the traveling wave approach is forbidden for clinical MR systems due to their much lower field, and therefore, hard-to-fulfill cut-off requirements. Here, we demonstrate a quasi-static field regime allowing traveling wave concept to be applied in 3T clinical system. We demonstrate MR images of phantoms and human leg with large field of view that are comparable to the ones obtained in ultra-high field scanners (>7T) using traveling wave approach.
