Model Morphology Data.zip.

A set of two files per subject containing the morphology and connectivity information of the airway tree (both “real” and “model” data). The _morphology.txt file includes the total lung volume of the subject lung in cm3 and the %volume per lobe. It also includes the following fields in each row (one row per airway): (i) Vida_Name: The name assigned to each airway by the Vida PW2 software (0 if none exists), (ii) CenterLineLength: The distance between airway start and end coordinates in mm, (iii) Diameter: The airway average diameter in mm, (iv) Branching_Angle: the airway branching angle in degrees, (v) VidaGeneration: The generation assigned to each airway by the Vida PW2 software, vi) xs, ys, zs, xe, ye, ze: The coordinates of the start and end node of each airway in voxels, (vii) Adept_Names: The individualized naming scheme for each airway; in-house terminology is used, (viii) Generation: The airway generation assigned to each airway using a Boyden-based scheme, (ix) RootFlag: A flag indicating whether the airway is a “leaf” in the tree (1) or just a tree branch (0), (x) SpaceVolume: The volume of the space in the lung supplied by each airway in mm3. The translation.dico file contains information on airway connectivity, explicitly stating the parent-child relationships in the tree. (ZIP)
