| DAP (Gy · cm2) | Brain Equivalent Dose (mGy) | ED ICRP-10316 (mSv) | ED/DAP (mSv/[Gy · cm2]) | |
|---|---|---|---|---|
| Koyama et al (2010)19 | — | 14–37 | 0.47–1.2 | — |
| Kim et al (2012)17 | 5.99–9.61 | 5–6 | 0.38–0.87 | 0.06–0.09 |
| Bai et al (2013)18 | 9.4 ± 2 | 6 | 0.30 ± 0.08 | 0.03–0.035 |
| This study | 11.75–23.5 | 16–32 | 0.83–1.6 | 0.09 |
Note:—ED indicates effective dose estimated with the parameters from the document ICRP-103.

Kim et al and Koyama et al provide a range of dose estimations for several situations (kilovolt, collimation, or gantry tilt). Bai et al provide mean values ± SD for a sample of patients, except for the brain dose, for which they provide a phantom estimation.
