Purpose
Radiofrequency field inhomogeneity is a significant issue in imaging large fields of view in high‐ and ultrahigh‐field MRI. Passive shimming with coupled coils or dielectric pads is the most common approach at 3 T. We introduce and test light and compact metasurface, providing the same homogeneity improvement in clinical abdominal imaging at 3 T as a conventional dielectric pad.
