RECOGNITION AND CORRECTION OF MOVEMENT magnetic resonance imaging on a rigid, non-rigid, progressive, pivotal movement AND MOVING THROUGH THE PLANE

摘要

A magnetic resonance (MR) image reconstruction method comprises: compensating an MR imaging data set (36) for rigid subject motion based on comparison of reference k-space data (32) with region k-space data (34) acquired together with the MR imaging data set to generate an MR imaging data set (52) with rigid motion compensation; compensating the MR imaging data set (52) with rigid motion compensation for non-rigid subject motion by convolution with a kernel (82) embodying the at least one consistent correlation of k-space data of the MR imaging data set; and reconstructing the MR imaging data set with the compensation for rigid and non-rigid motion to generate a reconstructed subject image.
