1. A method for processing magnetic resonance imaging (MRI) data, comprising: receiving MRI data comprising a plurality of k-space points for an image data set; deriving a plurality of different versions of the image data set based on the MRI data, each of the plurality of different versions of the image set obtained by zeroing a different one of the plurality of k-space points; computing image space metric values for each of the plurality of different versions of the image data set; identifying zeroed ones of the plurality of k-space points for each of the plurality of different versions of the image data set for which the at least one image space metric value fails to meet a threshold value; and adjusting a portion of the MRI data associated with the identified zeroed ones of the plurality of k-space points to yield adjusted MRI data.
