NAME

vbrlbl − : airway anatomical labeling

SYNOPSIS

vbrlbl if= res= of= mf= gf= hf= [sf=] [rf=] [rs=] [ls=] [-d] [-v]

DESCRIPTION

vbrlbl assigns anatomical names (labels) to the segmented airway bronchi. It also generates the summary of airway dimension measurements (lumen diameter and wall thickness) for each labeled bronchus and for each generation respectively.

It takes a csv summary of each segmented bronchus as inputs. It assigns anatomical label to each airway bronchus following the topological order of the airway tree based on features including running directions and diameters. of, mf, hf and hf are the output csv summary files of the airway measurements. rs and ls are the optional output visionX vector of labeled airway skeletons used for fast visualizations.

If sf= and rf= are specified, the bronchus (labeled by topological label) in the input sf= are relabeled by its anatomical label and saved in the output rf=. rf may be used to update the organ map and vtk visualization.

OPTIONS

if=

csv file where each line for each airway bronchus: topological label, diameter (in mm), thickness(in mm), length(in mm), start(x,y,z), end(x,y,z) The total number of segments are specified in the first line.

res=

input xres,yres,zres scan resolution.

of=

output csv including all available information for each bronchus: anatomical label, anatomical name, diameter, length, wall thickness, start, end, direction, local direction, topological label. .

mf=

output csv including information for generation 0 to generation 9: generation #, count, average diameter, average wall thickness The average measurements are weighted by bronchus length.

gf=

output csv including 30 numbers to gather: count, average diameter and average thickness for each generation. The average measurements are weighted by bronchus length.

hf=

output csv including 36 numbers to gather: diameter and thickness for 18 3rd generation bronchi.

sf=

input short image with each bronchus labeled by its topological label.

rf=

output byte image with each bronchus labeled by its anatomical label.

rs=

optional VX_V3D vector of all labeled right bronchi for skeleton visualization.

ls=

optional VX_V3D vector of all labeled left bronchi for skeleton visualization.

-v

verbose mode.

-d

debug mode.
