Accurate RF coil localization is important for hyperpolarized 13C MRI. Fiducial markers can be constructed from 55Mn and localized using projection imaging. This study examines the minimum number of projections necessary to localize the markers subject to the known distances between markers. This would potentially allow marker localization to be automated as part of prescan.
