Dose and activity distributions calculated in a patent CT. (a) RBE-weighted dose map calculated with TRiP98, (b) absorbed dose and (c) annihilation maps calculated with FLUKA for a single-field 11C treatment plan optimized in a patient CT. Color bars reflect the respective distributions with red corresponding to the maximum observed values. (d) Normalized beam-eye-view profiles extracted from the dose and annihilation maps for the original treatment plan and those optimized using the scaled HLUT tables (for 3.5% or 1%) to mimic the range uncertainties. Depth is given in the CT coordinates. Blue solid lines: dose profiles, orange dashed lines – annihilation profiles. Left plot is a zoom-in of the distributions in the target region.
