Comparison of CBCT shifts and session time recorded following patient positioning with tattoos or SGRT.
| Vertical (cm) | Longitudinal (cm) | Lateral (cm) | Session time (min) | ||
|---|---|---|---|---|---|
| CBCT shifts post tattoo and laser setup (N = 236) | Average ± standard deviation | 0.3 ± 0.4 | −0.1 ± 0.6 | 0.0 ± 0.5 | 11.3 ± 2.1 |
| Median (min–max) | 0.3 (−1.2–1.3) | −0.1 (−2.1–1.5) | 0.0 (−2.1–1.4) | 11.3 (6.9–14.4) | |
| Q1–Q3 | 0.10–0.60 | −0.4–0.3 | −0.3–0.3 | 10.1–13.1 | |
| CBCT shifts post SGRT setup (N = 225) | Average ± standard deviation | 0.2 ± 0.2 | −0.1 ± 0.3 | 0.3 ± 0.2 | 10.9 ± 1.4 |
| Median (min–max) | 0.2 (−0.5–0.9) | 0.0 (−1.0–0.7) | 0.3 (−0.4–0.9) | 11.2 (7.0–12.7) | |
| Q1–Q3 | 0–0.4 | −0.3–0.2 | 0.1–0.4 | 10.0–12.0 | |
| t-test | p-value | < 0.0001 | < 0.0001 | < 0.0006 | 0.038 |
