Abstract:
1. A method of magnetic resonance (=MR) imaging for acquiring images of an object through sampling, on grids in time, a magnetic resonance signal radiated from the object, thereby obtaining sampling points, the method comprising the steps of: a) applying non-linear gradient fields for spatial encoding; b) completely imaging the object in regions of stronger gradient fields by increasing a density of the sampling points in a center of k-space such that a resulting measurement resolution is sufficient in those reactions of stronger gradient fields; c) specifically acquiring additional sampling points in outer regions of k-space according to a k-space sampling pattern and in dependence on a desired distribution of measurement resolution in real space; and d) calculating an MR measurement result using the additional sampling points, wherein the MR measurement result has a desired distribution of measurement resolution that deviates from a distribution of measurement resolution given by the non-linear gradient fields.
