Patent ID: 8072215

Claim:
A device for MR imaging of a body placed in an examination volume, the device comprising: a magnet which establishes a substantially homogeneous main magnetic field in the examination volume; gradient field magnets which superimpose magnetic field gradients upon the main magnetic field; an RF source which radiates RF pulses towards the body; a controller which controls the gradient field magnets and the RF source to generate an RF pulse followed by a plurality of switched magnetic field gradients, the switched magnetic field gradients being controlled to produce at least two sub-sequences of MR echo signals, each sub-sequence traversing a different trajectory in k-space with subsampling in a phase encoding direction; two or more receiving antennas for receiving the MR echo signals from the body, which receiving antennas have sensitivity profiles a reconstruction processor which reconstructs an MR image from the MR echo signals and from the phase/amplitude correction maps associated with sub-sequences of MR echo signals and from sensitivity profiles of the receiving antennas.
