Abstract

An iterative reconstruction is performed of multiple gradient echo MR imaging data to generate a reconstructed MR image (). The iterative reconstruction uses a model () that links the MR imaging data and the reconstructed MR image. The model includes a parameterized magnetic field fluctuation component (). During the performing of the iterative reconstruction, parameters of the parameterized magnetic field fluctuation component of the model are updated to optimize a cost function () dependent on partial derivatives of the reconstructed MR image with respect to the parameters of the parameterized magnetic field fluctuation component of the model. The image may be further processed to generate an R2* map (), an SWI image (), or a QSM map ().
