3D analysis of chest CT using SYNAPSE VINCENT. (A) Lung lobe extraction and segmentation. (B) Low attenuation area (LAA%) distribution analysis, the closer to red means more severe emphysema, the closer to blue means less severe emphysema. (C) 3D CT reconstruction image of the airway tree. (D) Cross-sectional images of selected airways, with the red line indicating the outer wall and outer diameter of the airway and the green line indicating the inner wall and inner diameter of the airway. (E) Longitudinal section image of the selected airway, yellow dots are automatically marked branch points
