Machine Model: Adjustable Parameters
 What does the modulating:
 Pencil beams (“beamlets” )
 Aperture shape & MU’ s (“Segments”)
 More general
 e.g, gantry angles, dose rate, motion control etc.
 Certain parameters are assigned manually:
 Number of beams, orientation
 Gantry, collimator, table angles
 Certain parameters are machine specific:
 Mode of delivery (dynamic, step-shoot, tomotherapy)
 Collimation limits (leaf width and speed, etc)
