Advanced Physics for Brachytherapy 2018

Type B uncertainty … code

➢ What MC code should I use? / Should I prepare my own?

➢ Codes benchmarked and extensively used in the literature: PTRAN, MCNP, GEANT4, PENELOPE, and EGS.

➢ TG-43U1*: Monte Carlo codes not previously used in brachytherapy dosimetry, should be more rigorously tested and documented in the peer-reviewed literature before proposing to use their results clinically. ➢ TG-43U1*: “regardless of the transport code chosen and its pedigree, all investigators should assure themselves that they are able to reproduce previously published dose distributions for at least one widely used brachytherapy source model. This exercise should be repeated whenever new features of the code are explored, upon installing a new code version, or as part of orienting a new user.”
