Fig. 2From: Generating synthetic CT from low-dose cone-beam CT by using generative adversarial networks for adaptive radiotherapyQuality comparison of CBCT, CT, and sCT images generated by three neural networks for the same patient in axial, coronal, and sagittal images. The display window in second row is [− 1200 300] HU (lung window), and display window in other rows is [− 400 400] HUBack to article page
