A method for performing correction in an autocalibrated, multi-shot MR
imaging data acquisition includes performing correction on k-space data
in an autocalibration region for each shot individually and then
combining the corrected k-space data from each shot to form a corrected
reference autocalibration region. Uncorrected source k-space data points
are "trained to" the corrected k-space data from the corrected reference
autocalibration region to determine coefficients that are used to
synthesize corrected k-space data in the outer, undersampled regions of
k-space. Similarly, acquired k-space lines in the outer, undersampled
regions of k-space may also be replaced by corrected synthesized k-space
data. The corrected k-space data from the corrected reference
autocalibration region may be combined with the synthesized corrected
k-space data for the outer, undersampled regions of k-space to
reconstruct corrected images corresponding to each coil element. The
corrected images corresponding to each coil element may be combined into
a resultant image.
