Claim One:
1. A method of image reconstruction of MRI data from a plurality of receiver coils comprising the steps of: a) obtaining k-space data with each of the receiver coils, the data being on a plurality of trajectories in k-space, the k-space data being oversampled in a region near the origin of k-space (central region) corresponding to lower frequencies, b) for each coil, establishing k-space data in a full field of view set using k-space data measured by each coil and k-space data measured from other coils, c) for each coil establishing k-space data on a k-space location in the full field of view set using a linear combination of measured k-space data in a pattern of k-space locations around a k-space location in the full field of view set, d) determining the linear combination weights for step c) by identifying in the central region a plurality of instances of the same or similar patterns of k-space locations around a k-space location having synthesized k-space data, the synthesized data being derived from measured k-space data in the central region for each coil, e) Fourier transforming k-space data on a full field of view for each receiver coil to provide an image for each receiver coil, and f) combining images for all coils to form a composite image.
