Patent ID: 8649579

Claim:
A non-transitory computer-readable medium storing computer-executable instructions that when executed by the computer cause the computer to perform a method, the method comprising: controlling a magnetic resonance imaging (MRI) apparatus to acquire a fully sampled, centric ordered, non-interleaved, data set from an object to be imaged; controlling a Generalized Auto-Calibrating Partially Parallel Acquisition (GRAPPA) logic to produce a GRAPPA duplicate of a single partition through the data set; computing, from the GRAPPA duplicate, a GRAPPA navigator for a phase encoding (PE) line in the single partition; and selectively replacing data in the PE line in the single partition with replacement data in response to determining that a comparison of the PE line in the single partition and a corresponding PE line in the GRAPPA duplicate indicates that data in the PE line has been motion corrupted, where the comparison is based, at least in part, on the GRAPPA navigator.
