摘要:
A novel magnetic resonance imaging method is presented for forming an image of an object from a plurality of signals acquired by an array of multiple receiver antennae. Prior to imaging a sensitivity map of each of the receiver antennae is provided, at least two adjacent antennae record signals originating from the same imaging position and the image intensity is calculated from the signals measured by different antennae, wherein the number of phase encoding steps is reduced with respect to the full set thereof. In addition the field of view is set smaller than the object size in phase encoding direction inducing intrinsic foldover artefacts, whereas the sensitivity map of the receiver antennae and a reference image featuring intrinsic foldover artefacts are used for reconstruction of the MR image to an unfolded image.
