Take home message:
image-guidance for breast cancer
•
MV can be acceptable is you have a good surrogate (e.g.
visible clips, not only ribs)
•
The less robust your treatment technique, the more advanced
the IGRT
•
For robust treatments, an offline strategy (NAL, eNAL, SAL,
etc…) will go a long way towards reducing uncertainties
•
Surface image has interesting potential and properties (no
dose) but shouldn’t be the only modality for set-up (rotations,
DIBH…)
•
Deep inspiration: just do it !
