Patent ID: 7439739

Claim:
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 k-space 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 given k-space location in the full field of view sets; d) determining linear combination weights for step c) using synthesized k-space data and by identifying in the central region a plurality of instances of the same or similar patterns of k-space locations around the given k-space location using the synthesized k-space data, the synthesized k-space data being derived from measured k-space data in the central region of each coil, and wherein the synthesized k-space data differs from the measured k-space data: e) Fourier transforming the k-space data on a the full field of view for each receiver coil in order to provide an MRI data image for each receiver coils; and f) combining the images for all coils in order to form a final composite MRI data image.
