IMRT QA - The pessimistic point of view
We are forced to do it for
every
patient because we are
not confident enough in our equipment
It takes an awful lot of time
This gamma acceptance criteria look very fancy, but do
they really check what they are meant to?
No one really knows when to stop (20th patient? 100th
patient? 101th?) People basically stop when they are
exhausted, which is not a very rational criteria.
Let’s face it: IMRT verification is one big mess.
