Why do we need dose optimization if all we want to do is dose planning?
What do we actually optimize? Dose? Cost functions? Beamlets?
What optimization algorithm to use, and why?
Weight Factors, Constraints, Objectives – why is it so complex?
What is the point in optimizing undeliverable fluence profiles first?
Why does the dose get worse after MLC sequencing? And isn
´
t direct aperture
optimization better anyway?
How much optimization is actually in an IMRT optimizer?
Cost functions: Which one to use when?
