Table 4 Mean absolute error and standard deviation (mean ± SD) for relevant dose-volume metrics on the target and several organs for lung cancer testing for the Mask and AB models. The values are expressed as a percentage of the prescription dose (ranging from 42.5 to 60 Gy) for the metrics reporting the dose received by x % of volume (D_x) and an absolute difference for the metrics reporting the volume (in %) receiving a dose of y Gy (V_y)
