A bespoke Gaussian-mixture distribution is used to model the long-tailed noise distribution in cases of brain hemorrhage and/or calcification QSM.
Robust Quantitative Susceptibility Mapping (QSM)
A bespoke Gaussian-mixture distribution is used to model the long-tailed noise distribution in cases of brain hemorrhage and/or calcification in QSM with automatic hyperparameter estimation (Huang et al., 2023).
Comparison of the recovered quantitative susceptibility maps using MEDI and the proposed AMP-PE approaches.
