A computer-implemented method for gradient delay time correction of MR data using an MR device, wherein the magnetic resonance data is recorded using a three-dimensional recording technique with linear recording trajectories which are oriented in different readout directions of a readout plane that is perpendicular to a partition direction. The method includes: in a calibration measurement using the magnetic resonance device, recording calibration data which describes readout-direction-dependent shifts, caused by delay effects, of measurement points in the k-space; determining correction data by evaluating the calibration data; correcting the MR data based on the correction data in order to compensate for the delay effects, wherein the calibration data, which covers a coverage region in partition direction is recorded in a resolved manner, and the correction data is determined and applied in a manner that is dependent on partition direction.
