Correlations between PTV and differences among the three radiation techniques in mean lung dose (MLD) for the total lung. ΔMLD stands for the differences between two radiation plans in MLD. For the patients with smaller volumes, the three radiation plans were comparable, but for larger volumes, VMAT showed the better MLD compared with TOMO and IMRT plans in MLD.
