Summary & Conclusions
•
IMRT treatment planning means
exploring the limits of
physics
for each patient
:
- the ‘physics in the patient’: Is the desired dose distribution possible?
(steepness and placement of gradients,…)
- Applicability by MLC hardware
•
numerous different and partly conflicting target and normal tissue goals
need to be balanced —

‘navigation’
: using weight factors, constraints, or a library of
precalculated plans
