Claim 0:
1. A method of magnetic resonance (MR) imaging of an object positioned in an examination volume of an MR device, the method comprising:
subjecting the object to an imaging sequence comprising at least one RF excitation pulse and sinusoidally modulated magnetic field gradients,
selecting two or more spiral k-space trajectories, wherein the origins of the spiral k-space trajectories are offset from each other in a plane of the spiral k-space trajectories, wherein the offset spiral k-space trajectories are overlapping in a region around k-space origin, wherein the origins of the spiral k-space trajectories are at least one of (i) offset from k-space origin, (ii) equally spaced from k-space origin, and (iii) symmetrically arranged around k-space origin, wherein each spiral k-space trajectory lies in a kx,ky plane and the origins of the spiral k-space trajectories are offset from each other along a direction parallel with the kx,ky plane;
acquiring MR signals along the two or more spiral k-space trajectories;
reconstructing an MR image from the acquired MR signals; and
displaying the MR image.
