Dose prediction for cervical cancer VMAT patients with a full-scale 3D-cGAN-based model and the comparison of different input data on the prediction results

Table 4 The average dosimetry results of OAR for 20 test patients. Three dosimetry indexs, \({D}_{max}\), \({D}_{mean}\), and \({V}_{40}\), are included

The bold values denote that the difference of the dosimetry indexes between the predicted and the clinical dose is not statistically significant
Annotate: \({D}_{max}\) and \({D}_{mean}\) denote the maximum and mean dose for the organs; \({V}_{40}\) denotes the maximum volume percentage receiving dose 40 Gy
