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
