Iterative Projection Onto Convex Sets for Quantitative Susceptibility Mapping

摘要

PurposeQuantitative Susceptibility Map (QSM) reconstruction is ill posed due to the zero values on the “magic angle cone” that make the maps prone to streaking artifacts. We propose Projection Onto Convex Sets (POCS) in the method of Steepest Descent (SD) for QSM reconstruction.
