Synopsis

When acquiring fat suppression sequences, active shimming can be used to reduce magnetic field inhomogeneities which are inversely related to image quality and cause image artifact. Active shimming improves image quality by optimizing the homogeneity on an individual patient basis to optimize the final shimming and directly, the resulting image quality.
