  • Note:—ED indicates effective dose estimated with the parameters from the document ICRP-103.

  • a 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.
