提出基于掩码的区域增长方法用于相位解缠。该方法中，残差用零像素点连接作为掩码，掩码和原始质量图结合构成新的质量图。利用这个新的质量图，在多个区域内各自对相位进行区域增长方式的解缠。通过调整偏移量将这些区域融合在一起。模拟和实际磁共振的数据被用来验证该方法。结果表明，与最新的区域增长相位解缠方法（PHUN）相比，采用该方法明显改善了解缠相位的准确度。

A mask‐based region growing approach was proposed for phase unwrapping .The residues were connected by zero‐value pixels that were then served as mask .The mask and the original quality map were combined into a new quality map .Guided by the new quality map ,unwrapping was conducted within multiple regions .The regions were merged by adjusting the offset between one another .Both simulated and real MRI data were used to verify the proposed algorithm .Results show the advantage of the proposed approach over the recent region‐growing phase unwrapping method (PHUN) in accuracy .
