Abstract
In a method and magnetic resonance (MR) system for the creation of an artifact-free image data set of an imaging area located in a measurement volume of the MR system, measurement data are acquired from which an image data is to be reconstructed, with gradients for spatially coding of the measurement data are ramped continuously over time to a strength desired for the acquisition of the measurement data, without abrupt changes in the gradient strength. The actual gradients present in the measurement volume are measured by a field mapping device in the measurement volume of the MR system. The trajectories along which k-space is scanned during the acquisition of the measurement data are calculated on the basis of the measured actual gradients. An artifact-free image data set is reconstructed from the acquired measurement data under consideration of the calculated trajectories, and is displayed and/or stored.
