Quantitative susceptibility mapping using plug-and-play alternating direction method of multipliers

Scientific Reports, 2022
Quantitative susceptibility mapping employs regularization to reduce artifacts, yet many recent denoisers are unavailable for reconstruction. We developed a plug-and-play approach to QSM reconstruction (PnP QSM) and show its flexibility using several ...
