Computer-Implemented Method for Gradient Delay Time Correction, Magnetic Resonance Device, Computer Program and Electronically Readable Data Medium

A magnetic resonance device, comprising:

• a receiving area configured to receive an object for a magnetic resonance imaging examination;
• and
• a controller configured to perform gradient delay time correction of magnetic resonance data by:
• recording the magnetic resonance data using a three-dimensional recording technique with linear recording trajectories that are oriented in different readout directions of a readout plane that is perpendicular to a partition direction;
• recording, in a calibration measurement via the magnetic resonance device, calibration data that covers a plurality of partitions in the partition direction and describes readout-direction-dependent shifts, which are caused by delay effects, of measurement points of sampled k-space sections in k-space;
• determining correction data by evaluating the calibration data;
• correcting the magnetic resonance data based upon the correction data to compensate for the delay effects;
• and
• generating, from the corrected magnetic resonance data, magnetic resonance image data sets,
• wherein the calibration data, which covers a coverage region in the partition direction, is recorded in a resolved manner in the partition direction, and
• wherein at least one acceleration technique is applied in the partition direction during the recording of the calibration data.

An non-transitory computer readable medium having instructions stored thereon that, when executed by a controller of a magnetic resonance device, cause the magnetic resonance device to perform gradient delay time correction of magnetic resonance data by:

• recording the magnetic resonance data using a three-dimensional recording technique with linear recording trajectories that are oriented in different readout directions of a readout plane that is perpendicular to a partition direction;
• recording, in a calibration measurement via the magnetic resonance device, calibration data that covers a plurality of partitions in the partition direction and describes readout-direction-dependent shifts, which are caused by delay effects, of measurement points of sampled k-space sections in k-space;
• determining correction data by evaluating the calibration data;
• correcting the magnetic resonance data based upon the correction data to compensate for the delay effects;
• and
• generating, from the corrected magnetic resonance data, magnetic resonance image data sets,
• wherein the calibration data, which covers a coverage region in the partition direction, is recorded in a resolved manner in the partition direction, and
• wherein at least one acceleration technique is applied in the partition direction during the recording of the calibration data.
