The method may further include determining a respective phase difference for reference points along a respective position space line in the position space that extends in the respective gradient direction based on the first and second magnetic resonance data, and providing the phase differences of at least one subgroup of the reference points as correction information or ascertaining the provided correction information based on the phase differences of at least the subgroup of the reference points.

Abstract: In method for MR imaging, an MR signal is acquired for each of a plurality of readout gradient pulses during a respective readout period and an MR image is generated on the basis thereof. A start time of the respective readout period relative to a start time of the respective readout gradient pulse is delayed by a delay duration which is selected randomly or pseudo-randomly from two or more predefined time values, and/or to generate the MR image, the acquired MR signals are processed, wherein the processing includes a frequency conversion based around a center frequency which is randomly or pseudo-randomly selected from two or more predetermined frequency values.

Abstract: The disclosure relates to gradient delay time correction of magnetic resonance data. For recording the magnetic resonance data, use is made of a three-dimensional recording technique with linear recording trajectories oriented in different readout directions of a readout plane that is perpendicular to a partition direction. Calibration data is recorded which covers a plurality of partitions in partition direction and which describes readout-direction-dependent shifts, caused by delay effects, of measurement points, e.g. sampled k-space sections in the k-space. Correction data is determined by evaluating the calibration data, and the magnetic resonance data is corrected on the basis of the correction data in order to compensate for the delay effects. The calibration data, which covers a coverage region in partition direction, is recorded in a resolved manner in partition direction, and at least one acceleration technique is applied in the partition direction during the recording of the calibration data.
