Why patient-specific QA?
The agreement between planned and delivered dose may depend on
plan-specific parameters, like the level of modulation
Seems unavoidable at least until:
•
Stable history of machine QC for dynamic MLC and gantry
•
Monte Carlo dose calculation algorithm
•
Convenient secondary dose calculation
•
Extensive experience of high pass rates for patient-specific plan
measurements
•
New history of patient-specific QA needs to be aquired after new
class solution is introduced
