Inverse-planning: you only get what you ask for
•
Inverse planning is not a magic bullet: it does not remove dose, it
redistributes it
•
Talk to your computer:
-
contour as much as clinically relevant
- use constraints on the low dose bath (ex V5Gy for the lung, as
low as possible for the heart)
•
Be careful when reviewing the literature:
- what compromise did they accept? (contralateral lung?)
- what dose level are they looking at? (at V20 or V30, IMRT looks
often
better than 3D-CRT… but this is not the whole picture!)
- what is their target coverage criterion (CTV/PTV)
