Example of a submitted dataset with contours graded overall as major deviation, (A) axial, (B) coronal and (C) sagittal views. GTV-pt not included in its entirety in all CTVs. Contralateral level IB-IV not included in CTV52.8 Gy, level V not adequately included, and level IA included erroneously. For normal tissue contours, medulla (instead of entire brainstem) and spinal cord (instead of spinal canal) contoured (not shown). 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.
