TABLE V.
Mean ± one standard deviation of the measured SSQ for each airway. The standard deviation was calculated based on data from five interleaved slices. The p value was given by a paired t-test between the SSQ values of FBP and MBIR.
| Airway index | Nominal WT (mm) | SSQ of FBP (mm2) | SSQ of MBIR (mm2) | p value |
|---|---|---|---|---|
| 1 | 4.5 | 1.8 ± 0.4 | 0.12 ± 0.01 | 0.001 |
| 2 | 3.5 | 0.9 ± 0.2 | 0.04 ± 0.01 | 0.002 |
| 3 | 2.7 | 0.24 ± 0.04 | 0.12 ± 0.05 | 0.01 |
| 4 | 2.3 | 0.19 ± 0.02 | 0.09 ± 0.04 | 0.001 |
| 5 | 1.8 | 0.35 ± 0.05 | 0.17 ± 0.07 | 0.004 |
| 6 | 1.3 | 0.6 ± 0.3 | 0.26 ± 0.09 | 0.07 |
| 7 | 0.8 | 0.4 ± 0.2 | 0.47 ± 0.06 | 0.3 |
