vairmatch − matches airway segment across scan pair
SYNOPSISvairmatch if1=<ifile> if2=<ifile> ig1=<ifile> ig2=<ifile> bp1=<ofile> bp2=<ofile> of=<ofile> [-db] [-v]
DESCRIPTIONvairmatch matches airway segments across two scans of same patient. The program takes in two CT scans (if=), the skeletons of the airway trees (ig=), and the airway branch information file (bp=). The branch information file for each scan must be obtained from vbronch.
The program tries to match corresponding segments across the scans by performing registration between spherical regions around the segment’s end points. The output is the text file with each line containing following information on the matched segment:
<ID> <ID1> <ID2> <start1> <end1> <start2> <end2> <MSE> <length1> <length2>
* ID1 and ID2 are the segment IDs from scan 1 and scan 2, respectively.
* start1 and start2 are the starting coordinate <x,y,z> of the segment for scan 1 and scan 2, respectively.
* end1 and end2 are the ending coordinate <x,y,z> of the segment for scan 1 and scan 2, respectively.
* MSE is the similarity (mean squared error) between two spherical regions
* length1 and length2 are the lengths of the segments for scan 1 and scan 2, respectively.
