Results According to our analysis, the results of 3D in-vivo dosimetry for each technique and treatment region met the protocol value except for γ mean values of the lung treatment as presented in Table 1. Nevertheless, γ mean values for lung treatment met the proposed minor variation criteria for both techniques. Representative dose line graphics for measured and calculated dose distribution in 3D-CRT total lung irradiation were illustrated in Figure 2.
