Abstract

In a method for generating at least one MR image of an object in an MR system comprising a plurality of signal receiving coils, a sequence of RF pulses are applied in order to generate a plurality of MR signal echoes, the MR signal-echoes are detected with the plurality of signal receiving coils in a 3-dimension-al k-space, and the at least one MR image is reconstructed using the non-homogeneous under sampled 3-dimensional k-space based on a compressed sensing technology. The 3-dimensional k-space may be undersampled with a plurality of constant radii corkscrew trajectories having different radii resulting in a non-homogeneous undersampled 3-dimensional k-space.
