Abstract:
A novel magnetic resonance imaging method is described, wherein the object to be imaged is segmented into a region of slow variation and into a region of fast variation which defines a restrictive dynamic FOV. The object in the overall FOV is sampled in k-space with a reduction factor. The k-space sampling positions in the region of fast variation are transformed by Fourier Transformation to the spatial domain and are transformed additionally to the temporal-frequency domain. Further the positions in the temporal-frequency domain derived from the sub-sampled positions in k-space are unfolded on the basis of the spatial coil sensitivity profiles of the set of receiving coils, whereas the parts of the temporal-frequency domain related to the region of slow variation are set to zero, and the resulting data in the temporal-frequency domain is Fourier transformed to the temporal domain.
