A new method for retrospectively correcting subtle transverse slice-to-slice motion in a set of overlapped axial slices is introduced. Such motion can be problematic for high through-plane resolution imaging of the pelvis due to peristalsis of the rectum. The method exploits the known slice-to-slice correlation to determine offsets as well as characteristics of the multi-pass acquisition. When applied to 16 T2-weighted fast spin-echo exams of the prostate the method shows significant improvement in prostate-rectum margin clarity and overall image quality as assessed on sagittal reformats from axial images.
