Fig. 4.

The structure of MTCGSN. In this image, G represents the Generator, D represents the Discriminator, and T represents the Transforming Network, which transforms the synthesized HU image into lung window and mediastinal window images. In this structure, the transformed lung window image is used as the input for the subsequent parts. Additionally, C represents the Classification Network. By combining the results from two C networks, we determine the class result indicating whether the nodule is malignant
