AbstractThe generalized approach to parallel MRI has indicated that the utilization of acquired k-space points for GRAPPA reconstruction can be more flexible, including the points in frequency encoding direction. To investigate the optimal utilization of acquired k-space points in GRAPPA, the neighbor GRAPPA which incorporates several neighbor points to estimate each missing point is compared with the conventional GRAPPA by simulations and experiments. It is discovered that the optimal reconstruction scheme should depend on the geometry of the receive coil array and the orientation of FOV.
