Abstract
Systems, methods, and other embodiments associated with removing motion artifacts from MR images are described. One example method includes controlling an MRI apparatus to acquire a fully sampled, centric-ordered, non-interleaved, data set from an object to be imaged and controlling a Generalized Auto-Calibrating Partially Parallel Acquisition (GRAPPA) logic to produce a GRAPPA duplicate of a single partition through the data set. The method also includes computing, from the GRAPPA duplicate, a GRAPPA navigator for a phase encoding (PE) line in the single partition and computing an error between the PE line in the single partition and a corresponding PE line in the GRAPPA duplicate using the GRAPPA navigator. The method also includes selectively replacing data in the PE line in the single partition with replacement data upon determining that the error exceeds a threshold. The method may include reconstructing an MR image based, at least in part, on the single partition.
