Acquistion and reconstruction method for MR motion imaging and correction
A Cartesian 3D random Gaussian ESPReSSo subsampling is proposed which acquires a random combination of k-space lines ky and kz in each repetition, as illustrated in the Figure below. Periodically the central k-space lines are acquired which serve as a self-navigation signal in the reconstruction.
