In this study, we proposed a novel single-channel shim coil design method using circular current elements to correct higher order inhomogeneities. We succeeded in decreasing PP value of the B0 by 40%. In conclusion, the novel SCSC design method is simple and useful for shimming a B0 including higher order terms.
