  1. CTV: Clinical target volume; D90: dose delivered to 90% of the CTV; EQD2 αβ10: equivalent dose at 2 Gy per fraction for αβ10 (tumor); EQD2 αβ3: equivalent dose at 2 Gy per fraction for αβ3 (normal tissues); V100: volume which received 100% of the prescribed dose; V150: volume which received 150% of the prescribed dose; V200: volume which received 200% of the prescribed dose; DHI: dose homogeneity index.
