    • Required query elements include referenced objects
    • Modalities themselves (Planners, Contourers) may also support Q/R of RT Objects
  • 23. RT Plan Profiles
    • Profiles will be specified in terms of beam delivery types.
    • Each beam type supports a subset of modifiers.
    • Conformance will be specified with respect to the beam type profile and supported modifiers.
  • 24. RT Plan Conformance
    •
