Quantitative susceptibility mapping (QSM) of the cardiovascular system: challenges and perspectives
Journal of Cardiovascular Magnetic Resonance, 2022 Quantitative susceptibility mapping (QSM) is a powerful, non-invasive, magnetic resonance imaging (MRI) technique that relies on measurement of magnetic susceptibility. So far, QSM has been employed mostly to study neurological disorders characterized by

Iterative Restoration of the Fringe Phase (REFRASE) for QSM [PDF]
Frontiers in Neuroscience, 2021 In quantitative susceptibility mapping (QSM), reconstructed results can be critically biased by misinterpreted or missing phase data near the edges of the brain support originating from the non-local relationship between field and susceptibility. These data either have to be excluded or corrected before further processing can take place.

Quicksilver Scalable Multicast (QSM) [PDF]
2008 Seventh IEEE International Symposium on Network Computing and Applications, 2008 QSM is a multicast engine designed to support a style of distributed programming in which application objects are replicated among clients and updated via multicast. The model requires platforms that scale in dimensions previously unexplored; in particular, to large numbers of multicast groups. Prior systems werenpsilat optimized for such scenarios and

Feasibility of QSM in the human placenta
Magnetic Resonance in Medicine, 2020 PurposeQuantitative susceptibility mapping (QSM) is an emerging tool for the precise characterization of human tissue, including regional oxygenation. A critical function of the human placenta is oxygen transfer to the developing fetus, which remains difficult to study in utero.

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 ...
