相位展开是从波的模2 p值重建波的原始真实相位。它起源于各种应用，如合成孔径雷达，磁共振成像和自适应光学。在这篇文章中，二维相位展开的问题的定义和解决的挑战。各种既定的方法的问题进行审查和比较，并讨论其优点和缺点。在众多相位展开应用中，本文重点介绍了磁共振成像，并解释了相位展开如何用于场映射、反演恢复和流成像。Shankar gkramu /货号ebs 1356 1^12
Phase unwrapping is the reconstruction of the original true phase of a wave from its modulo 2p values. It originates in a variety of applications, such as synthetic aperture radar, magnetic resonance imaging, and adaptive optics. In this article, the problem of two-dimensional phase unwrapping is defined and the challenges are addressed. A variety of established approaches to the problems are reviewed and compared, and their advantages and disadvantages are discussed. Among the many phase unwrapping applications, the article focussed on magnetic resonance imaging and explains how phase unwrapping is used in field mapping, inversion recovery, and flow imaging.
