Fig. 2From: Vocal-cord Only vs. Complete Laryngeal radiation (VOCAL): a randomized multicentric Bayesian phase II trialExamples of VC-RT volumes in axial and sagittal view showing for a patient with right T1a glottic cancer (LEFT) and for a patient with T1b glottis cancer (RIGHT). The entire involved vocal cord (in T1a) or both vocal cords (in T1b) form the CTV (red); the ITV formed by an isotropic margin of 6 mm around the CTV (yellow) and the PTV is formed by additional 2 mm margin (green)Back to article page
