MAGNETIC RESONANCE METHOD FOR FORMING A FAST DYNAMIC IMAGE

Magnetic resonance imaging method and apparatus which employ multiple magnetic resonance signals from an array of multiple sensors or coils for the reconstruction of images. The method is used in fast dynamic MR imaging. Prior to formation of fast dynamic images, a normal magnetic resonance image with a full set of phase encoding steps is acquired for each sensor or coil. A subset of phase encoding trajectories is extracted commensurate with the phase encoding trajectories obtained by the fast dynamic imaging and an image is reconstructed from the subset. Subsequently, the signals of the fast dynamic image are compared with the signals of the reconstructed image, thus yielding an estimate of the fold-over artefacts of the fast dynamic image. The signals of the fold-over artefacts thus compensate the signals obtained by the fast dynamic imaging and deliver a corrected image without artefact parts.
