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

Figure 5

The top row is the branch-cut distribution for the MRI heart phase image in Figure 4(a) achieved using (a) dPSO, (b) Goldstein’s, and (c) MCM algorithms. The middle is the corresponding unwrapped phase result of (d) dPSO, (e) Goldstein’s, and (f) MCM algorithms. The bottom is the corresponding difference map of (g) dPSO, (h) Goldstein’s, and (i) MCM algorithms.
