Figure 3From: A dosimetric comparison of volumetric modulated arc therapy (VMAT) and non-coplanar intensity modulated radiotherapy (IMRT) for nasal cavity and paranasal sinus cancerMean dose volume histograms (DVHs) for planning target volume (PTV) and organs at risk in volumetric modulated arc therapy (VMAT) and non-coplanar intensity modulated radiotherapy (IMRT) using 7-, 11-, and 15-beams. (A) PTV; (B) ipsilateral optic nerve; (C) contralateral optic nerve; (D) optic chiasm; (E) brainstem; (F) ipsilateral eye; (G) contralateral eye; (H) ipsilateral lens; (I) contralateral lens; (J) ipsilateral lachrymal gland; (K) contralateral lachrymal gland; (L) ipsilateral parotid gland; and (M) contralateral parotid gland.Back to article page
