[Insight-users] Segment airway

[Luis Ibanez]

Hi SuperZZ,

We have managed to do airways segmentation
by using the Threshold connected filter and using
700 HU as the threshold value (from CT images).

See details in the Lesion Sizing Toolkit:

http://public.kitware.com/LesionSizingKit/index.php/Main_Page


It will, of course, connect to the outside air, but
that's easy to solve by cropping the image to
contain only the chest region, up to the patient's
throat.

What threshold value are you using ?

Have this CT image been preprocessed ?


    Please let us know,


        Thanks


              Luis

BTW: Maybe a screenshot of the leakage
may help us to see what is going on....
