Robust Magnetic Field Homogeneity Enhancement via Local Passive Shimming in a Superconducting Magnet for Animal MRI
H.S. Chen, Yaohui Wang, Wenchen Wang, Hui Wang et autres
In ultrahigh-field magnetic resonance imaging (MRI) systems, achieving subppm static magnetic field homogeneity is critical. However, engineering tolerances and assembly errors often introduce complex field inhomogeneities that global shimming alone cannot always fully correct. In this study, a novel local passive shimming …
