Fig. 4

Conventional (a) and VMI 40 keV (b) axial SDCT images of case 3 malignant tracheal lesion. The recurrent tracheal malignancy (white arrow) is enhanced in the 40 keV VMI compared to conventional CT. 3D volume rendering and segmentation of the bronchial tree from the 40 keV VMI data (c) also demonstrates good definition of the tracheal lesion (black arrow). (d) 3D printed bronchial tree from the 40 keV VMI data at 50% scale. The Formlabs Form 2 with standard clear resin was used and the tracheal lesion indentation was marked with black ink for visualization
