What are the changes/compromises?
The beam has a time structure
(possible impact on dosimetry)
Compact gantry
→
- more couch rotations
(possible impact on accuracy and
treatment time)
- does not allow for a 360°
CBCT acquisition
Smaller field size
→
- More «patched» fields are
needed
- Increased treatment time in
some cases (e.g. CSI)
