Abstract:
1. A magnetic resonance imaging method for forming an image of an object, wherein a stationary magnetic field and temporary magnetic fields having a position dependent field pattern are applied, magnetic resonance signals are acquired by at least one receiver antenna, spins are excited in a part of the object, MR signals are acquired in a sub-sampling fashion during application of the position-dependent field patterns, the magnetic resonance signals being sub-sampled by means of an array of receiving antennae, a magnetic resonance image is derived from the sub-sampled magnetic resonance signals, the magnetic resonance image being derived from the sub-sampled magnetic resonance signals on the basis of the spatial sensitivity profiles of the array of receiving antennae, and the position dependent field patterns are substantially non-linear, the number N of total field patterns is larger than 3, and at least N−1 field patterns are independently controllable in field strength.
