Lung Vessels module

Another way to achieve vessel segmentation is to use the “Grow from Seeds” function in the “Segment Editor”. More manual work, but you get additional airways and lung shadow. I usually define lungs, trachea and bifurcation, pulmonary artery, pulmonary vein and “Other” (paint a circle around the thorax in all axes) with a few paint strokes. Select “Grow from Seeds” and “Initialize”. Correct the results by adding a few paint strokes here and there. Press “Apply”. Go “Segments” and reduce the lung opacity.
