Abstract
Systems and methods for producing motion-corrected MR images that include an MRI scanner with a plurality of coils in which the plurality of coils is configured to detect a plurality of MR imaging datasets are provided. Each MR imaging dataset includes a plurality of MR signals detected by one coil of the plurality of coils. The system further includes a controller operatively coupled to the MRI scanner that includes at least one processor and a non-volatile memory. The controller further includes an image processing unit configured to receive the plurality of MR imaging datasets associated with the plurality of coils, identify a motion cycle using an automated motion detection method, and to partition the plurality of MR imaging datasets into a plurality of image groups, in which each image group comprises a portion of the plurality of MR imaging datasets associated with one of the phases of the motion cycle.
