Wavelet-based multigrid phase unwrapping method and its application to MRI phase image processing

摘要

This paper present a wavelet-based multigrid phase unwrapping method Tor MRI phase image processing. Based on the multiresolution property of the multigrid method, wavelet transform is incorporated into the multigrid phase unwrapping scheme. Preliminary results and analysis are presented. Possibility for an additional task-level parallelism in the algorithm is explored.
