Robustness for Small and Large Thorax Phantoms and for Each Reconstruction Algorithm
| Algorithm | Rb for small thorax phantom | Rb for large thorax phantom | Ro |
|---|---|---|---|
| AD | 0.0806 | 0.0811 | 0.0889 |
| ADS-TEW | 0.0816 | 0.0823 | 0.0956 |
| ADS-MC | 0.0569 | 0.0689 | 0.0731 |
The smaller the number, the less sensitive is the method to anatomic variations. Monte Carlo based reconstruction clearly outperforms the other methods in terms of robustness.
