Fig. 3From: A cycle generative adversarial network for improving the quality of four-dimensional cone-beam computed tomography imagesResults of the image quality test (a) and image deformation test (b). All images are shown with the same window width and levels. a-1 Degraded 4D-MSCT image, a-2 generated image, and a-3 original 4D-MSCT image. b-1 Original 4D-CBCT image in maximum exhalation, b-2 generated image, and b-3 4D-CBCT image in maximum intakeBack to article page
