Figure 1

Simulation portals depicting anatomical regions of interest (ROI). These were selected as “dose points” and centrally reviewed by MM and RTOG QA HQ to determine if dose points were clearly within the field, clearly outside of the field, or at the marginal edge of the field. A) Lateral simulation film and ROI points: Point 1 – Superior Oropharynx (soft palate), Point 2 – Inferior Oropharynx (Inferior Tonsil), Point 3 Superior Hypopharynx (AE fold). B) AP simulation film and plotted ROI; Point 4 – Inferior Hypopharynx (approximate location of the cricopharyngeus).
