In MRI data acquisition according to the GRASE (gradient and spin-echo) sequence, trajectories (562, 563) in k-space are arranged such that different coordinates (kx, ky) in that space have monotonic relations with parameters (t, tau ) that are related to physical effects, such as magnetic field inhomogeneities, T2 *-effects and motion, that causes artefacts in the image. By doing so, the artefacts are reduced.
