Effects of the beam modulating elements that need
to be modeled for high-precision dose calculation
•
leaf transmission, (jaw transmission)
•
inter-leaf leakage
•
leaf/jaw tip factors (influence on penumbra shapes)
•
tongue-and-groove

most of these effects were discussed in the presentations of Marco Schwarz:
“IMRT delivery techniques”
“TPS commissioning”
