An example of cumulative dose evaluation for IMRT treatments without daily image guidance (alignment to the surface markers or “BBs”on the immobilization device) (BB-IMRT), image-guided IMRT (IG-IMRT), and image-guided adaptive IMRT described in this investigation (adaptive IMRT). Due to setup error, BB-IMRT has a tendency to underdose CTV.
