Abstract
An MR image (14) is reconstructed from MR signals (1, 2, 3, 4) that are acquired in parallel by a plurality of receiving coils (5, 6, 7, 8) with incomplete sampling of the spatial frequency space. The reconstructed MR image (14) is calculated iteratively as the solution of a system of linear equations. To provide a more highly developed method for parallel SENSE imaging, an iteration process (15) begins with a starting image (9) which approximates to the MR image to be reconstructed (14), in such a way that undersampling artifacts are suppressed in the intermediate solutions of the system of equations that are obtained during the course of the iteration process.
