Conclusion – optimisation techniques
Manual
Conservative and “safe”
Iterative procedure
Dependent on experience of dose planner
Graphical
Fast for small adaptations and fine tuning after manual opt
Beware of:
-
dwell times
-
deviations from standard loading
Inverse
Fast
Requires extra contouring + manual adaptations
Beware of:
-
dwell times
-
high dose regions
-
dose to non-contoured tissue
-
deviations from standard loading
