Table 5 Mean pass rates of the 2D and 3D gamma in 10 patients with respect to the dose distribution obtained using the 4D-MSCT images

From: A cycle generative adversarial network for improving the quality of four-dimensional cone-beam computed tomography images

  Pass rate (%)
2D gamma (3%/2 mm) 3D gamma (3%/2 mm)
AX SAG COR
4D-CBCT 74.7 ± 10.7 75.2 ± 14.1 83.6 ± 6.1 76.5 ± 10.8
sCT 95.7 ± 4.7 94.8 ± 5.3 92.5 ± 5.5 96.2 ± 4.2

  1. The 2D gamma was evaluated in three dose distribution directions. The p value was calculated using a two-tailed t test comparing the results of the 4D-CBCT and sCT images
