Gamma analysis physically relevant?
•
What do we want to detect with patient-specific QA?
•
Do we have confidence in our MLCs?
–
Perhaps better addressed with machine QA
–
Thourough commissioning of IMRT with challenging plans and several
measurement systems
–
Constancy checks with challenging plan
•
Do we have confidence in our dose calculation algorithm?
–
Aware of limitations
–
Impact depends strongly on the individual plan
–
The gamma index seems to correlate with plan complexity/modulation
–
Gamma pass rates can probably highlight challenging cases
