A New Particle Swarm Optimization-Based Method for Phase Unwrapping of MRI Data

Figure 7

The top row is the unwrapped phase image for the MRI head phase image in Figure 6(a) achieved by (a) dPSO, (b) Goldstein’s, and (c) MCM algorithms. The bottom is the corresponding difference map got by (d) dPSO, (e) Goldstein’s, and (f) MCM algorithms.
