Reliable two-dimensional phase unwrapping method using region growing and local linear estimation

In MRI, phase maps can provide useful information about parameters such as field inhomogeneity, velocity of blood flow, and the chemical shift between water and fat. As phase is defined in the (−π,π] range, however, phase wraps often occur, which complicates image analysis and interpretation. This w...
