Advanced Physics for Brachytherapy 2018

Monte Carlo: summary

➢ !Monte Carlo based TPS not clinically available for brachytherapy yet!

➢ MC is the gold standard for single source dosimetry in brachytherapy (TG-43 data) ➢ Several public domain codes are available that have been extensively benchmarked, and ample literature/experience/recommendations are available ➢ Type B uncertainties associated with MC results for single source dosimetry are (mainly) user-related ➢ MC is inherently associated with a level of type A uncertainty

➢ MC is also used: •

to support source calibration,

• to correct experimental dosimetry results, • to provide input data to other classes of dose calculation algorithms • to provide reference dose distributions for the verification of TPS results
