Evidence exists to show that phase unwrapping performed before channel combination results in fewer artifacts (singularities, open ended fringe lines) than when phase unwrapping occurs after channel combination. We have implemented a fast and efficient pipeline designed to enable processing of multi-channel phase data. Specifically, non-iterative phase unwrapping and channel combination are employed within the pipeline that links the MR scanner to a DICOM server, which displays the final combined images, while preserving all metadata.
