Abstract:
1. A method for correction of artifacts in magnetic resonance (MR) resonance images, comprising: entering MR measurement data, acquired with a pulse sequence in which gradients are activated simultaneously during radiation of at least one non-selective excitation pulse, into a memory representing k-space; from a processor, accessing said MR measurement data in said k-space memory and, in said processor, determining a perturbation matrix on spatial data of the acquired MR measurement data, and said measurement data in k-space, and the gradients used in said sequence; in said processor, inverting said perturbation matrix to obtain an inverted perturbation matrix, and calculating a corrected image from the MR measurement data in k-space and the inverted perturbation matrix by a matrix multiplication of said inverted perturbation matrix with said MR measurement data in k-space; and making said corrected image available as a data file at an output of said processor.
