TABLE II.
Inputting the entire projection vs ROI results for the percentage of projections that were within 10% phase of each other for each Fourier technique as compared with the manual technique.
| Entire projection: Percentage of projections within 10% phase (%) | ROI: Percentage of projections within 10% phase (%) | |||
|---|---|---|---|---|
| Projections | FT—phase | FT—magnitude | FT—phase | FT—magnitude |
| Phantom RC = 3 s | 100.0 | 86.3 | 100.0 | 98.1 |
| Phantom RC = 6 s | 100.0 | 79.9 | 100.0 | 92.3 |
| Patient 1 | 92.5 | 98.7 | 97.6 | 98.7 |
| Patient 2 | 58.3 | 83.1 | 93.4 | 87.3 |
| Patient 3 | 83.2 | 96.1 | 94.1 | 95.7 |
