In a trajectory correction method and apparatus for k-space data points in magnetic resonance imaging, a magnetic resonance data acquisition unit is operated to execute a sampling sequence to obtain k-space to be corrected. Empirical points are selected used to divide k-space to be corrected into a central region and a peripheral region. The trajectories of the data points in the central region and the peripheral region are corrected and the sampling sequence is executed again, with the corrected trajectories, to obtain corrected k-space.
