Recently, there has been an impetus to develop ultra-low-field (ULF) MRI technologies, which present opportunities for low-cost and portable imaging in point-of-care scenarios. Balanced steady-state free precession (bSSFP) is a time-efficient imaging sequence yet its feasibility at ULF remains unexplored. In this study, we implemented bSSFP sequence at 0.055T, and successfully demonstrated phantom, brain and extremity imaging.
