Abstract
A method for correcting MRI motion artifacts and main field fluctuations. A series of data prints are acquired at read points along a radial axis to form a view ( ). Subsequent views define a NMR data set. A processor stores the NMR data set and reconstructs an image array from a stored NMR data set by; a) reconstructing the NMR data set along a radial axis; b) producing a correction data array including correction values where each of the correction values is calculated as a function of the corresponding stored NMR datum and the stored NMR datum for the intersection of the first and subsequent projection ( ) axes; c) applying the data in the correction array to the NMR data set to produce a final NMrR data set.
