Incomplete spectrum QSM using support information
Frontiers in Neuroscience, 2023 IntroductionReconstructing a bounded object from incomplete k-space data is a well posed problem, and it was recently shown that this incomplete spectrum approach can be used to reconstruct undersampled MRI images with similar quality to compressed ...
