An improved multigrid phase unwrapping method with embedded gradient re-estimation for MRI phase images

An improvement of the multigrid phase unwrapping (MGPU) method by embedding a gradient re-estimator is proposed. It is shown by an experiment with an MRI phase image that the method improves conventional MGPU result.
