Example of a submitted dataset with contours graded overall as minor deviation, (A) axial, (B) coronal and (C) sagittal views. Superior border of GTV-pt (orange) and CTVs insufficiently high. CTV52.8 Gy (magenta) should not extend outside platysma or into submental, pretracheal or sternocleidomastoid regions. PTVs should be carved out of normal structures oral cavity and larynx. Orange: GTV-pt. Magenta: CTV52.8 Gy. Pink: CTV59.4 Gy. Red: CTV66 Gy. Blue: PTV52.8 Gy-Exact*. Green: PTV2Exact*. Purple: PTV3Exact*. *PTVExacts denote PTVs collapsed inside the skin by 5 mm.
