Take home message for APBI/Boost:
Image-guidance for partial breast irradiation
Clips can be representative for
•
the location of the tumor bed
•
the location of the whole breast
Registering on clips is time-efficient and can allow for
margin reduction of the tumour bed PTV
kV-CBCT, MV-CBCT, 2D kV are equivalent in terms of
accuracy if registering on clips
➢
2D MV as well, if clips are visible
