"Quantitative susceptibility mapping (QSM) attempts to calculate the suscepti-\r\nbility distribution of tissue using magnetic resonance techniques. The purpose\r\nof this work is to find an image quality measure, which effectively prevents\r\nan over-smoothing of the susceptibility maps, when optimizing the parameters\r\nwith regard to this measure. Moreover, an algorithm to solve the inverse phase\r\nto susceptibility problem is introduced, which uses verified and mathematically\r\nfounded methods to compute the susceptibility distribution accurately. To achie-\r\nve this the shearlet transform, the generalized total variation and the method of\r\niterative re-weighting are used. Furthermore, a step is made towards application\r\nof QSM in clinical practise, namely the automatic selection of the regularization\r\nparameters. For this the method of unbiased predictive risk estimator is used.\r\nThe values of the image quality measures of the calculated susceptibility maps\r\nachieve throughout top rankings in comparison with the submitted algorithms\r\nat the 1th and 2nd QSM reconstruction challenge. Furthermore, the calculated\r\nsusceptibility maps are free from strong artefacts and their visual perception is\r\nin accordance with its good image quality values. Probably the anisotropic pro-\r\nperties of the shearlets lead to such an accurate calculation of local susceptibility\r\nsources."^^ . "2022" . . . . . . . "Janis"^^ . "Stiegeler"^^ .
