A simple post-processing algorithm is described to correct for station mis-alignment and intra-station discontinuities in signal intensity in whole-body diffusion weighted imaging. The technique is demonstrated on a volunteer study and on a patient data set. A significant improvement in image quality compared to currently available correction methods is observed in both cases.
