摘要:In a method and apparatus for the correction of artifacts in magnetic resonanceimages (MR) acquired with an MR pulse sequence in which gradients are switchedsimultaneously during the radiation of at least one non-selective excitation pulse,
measurement data acquired with the pulse sequence in k-space are loaded into aprocessor, in which a perturbation matrix is determined on the basis of spatial and k-space point data of the acquired measurement data and the gradients used during theexcitation. A corrected image is calculated from the acquired measurement data in k-space and the perturbation matrix, with the calculation of the corrected image including amatrix inversion of the perturbation matrix. The corrected image is then stored ordisplayed.
