Improving homogeneity in abdominal imaging at 3 T with light, flexible, and compact metasurface Open
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…
