Figure 3

Representative examples of annotated cavity and bronchiectasis. Thick-walled, thin-walled, and wall-less cavities are marked as a cavity, and the outer wall of the lesion edge is the boundary mark, while bronchiectasis annotation should concern bronchial dilatation with respect to different factors.

(a) NTM-LD cavity

(b) PTB-LD cavity

(c) NTM-LD bronchiectasis

(d) PTB-LD bronchiectasis
