Magnetic Resonance Fingerprinting (MRF) is a newly developed approach for accurate and efficient multi parameter mapping. This work proposes a balanced steady state free precession (bSSFP) based MRF framework which introduces different phase cycling (phc-MRF) to compensate for banding artifact induced by B0 inhomogeneity. The phc-MRF was tested in both phantoms and in vivo. The preliminary results show the robustness of the phc-MRF to banding artifacts while maintaining the precision of parameter estimation and B0 sensitivity.
