Advanced Physics for Brachytherapy 2018

Conclusion

• TG43 presents limitation for many clinical sites ➢ From a few % to many tens of % for shielded geometries

• Algorithms desperately needed for low energy brachytherapy: seeds or eBx ➢ Much larger effects expected • New approaches depend on going beyond TG43 ➢ Shielded and directional applicators ➢ Directional sources ➢ eBx and low energy brachytherapy.
