While strategies for handling cardiac and respiratory motion are well established for cardiac and abdominal imaging, the aperiodic and non-rigid deformations from bowel contractions can limit the ability to perform high-resolution imaging in the lower abdomen and pelvis. This work assesses the feasibility of using a retrospective, non-rigid motion-corrected averaging approach to reduce the impact of involuntary motion on anatomical MRI of the pelvis.
