A new method using stream function was proposed to correct inhomogeneity of the magnetic field with single-channel shim coils. The inhomogeneity achieved by the stream function method was comparable to that achieved by the target field method. Moreover, the inhomogeneity along z-axis was also corrected, which could not be done by the target field method. The method presented here provides large three dimensional homogeneity without multi-channel shim coils, which leads to the enlargement of available space for samples.
