Robust phase unwrapping for MR temperature imaging using a magnitude-sorted list, multi-clustering algorithm

Purpose Several methods in MRI use the phase information of the complex signal and require phase unwrapping (e.g., B0 field mapping, chemical shift imaging, and velocity measurements). In this work, an algorithm was developed focusing on the needs and requirements of MR temperature imaging applications. Methods The proposed method performs fully automatic unwrapping using a list of all pixels sorted by magnitude in descending order and creates...
