To perform magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS)in high and ultra-high field homogeneity of field (B0) is required to improve image quality and obtainable metabolic information form MRI scan. In this work we present, real shim field calibration to improve homogeneity of B0 field. The vendor implemented B0 shim system consists of one 0th order, three 1st order, five 2nd order and seven 3rd order shim coils. The proposed calibration to be implemented in existing stand-alone Philips system and further application software shall be developed to integrate latest algorithms and methods to B0 shimming.
