Results for the average difference in phase using the entire projection vs ROI for both Fourier techniques relative to the manual one.
| Entire projection: Average difference in phase (%) | ROI: Average difference in phase (%) | |||
|---|---|---|---|---|
| Projections | FT—Phase | FT—Magnitude | FT—Phase | FT—Magnitude |
| Phantom RC = 3 s | 1.8 | 7.4 | 1.8 | 2.1 |
| Phantom RC = 6 s | 3.7 | 9.3 | 3.9 | 4.0 |
| Patient 1 | 5.1 | 2.9 | 2.9 | 2.9 |
| Patient 2 | 15.5 | 6.8 | 5.0 | 5.3 |
