<br>Hi SuperZZ,<br><br>We have managed to do airways segmentation<br>by using the Threshold connected filter and using<br>700 HU as the threshold value (from CT images).<br><br>See details in the Lesion Sizing Toolkit:<br>
<br><a href="http://public.kitware.com/LesionSizingKit/index.php/Main_Page">http://public.kitware.com/LesionSizingKit/index.php/Main_Page</a><br><br><br>It will, of course, connect to the outside air, but <br>that's easy to solve by cropping the image to <br>
contain only the chest region, up to the patient's<br>throat.<br><br>What threshold value are you using ?<br><br>Have this CT image been preprocessed ?<br><br><br> Please let us know,<br><br><br> Thanks<br><br>
<br> Luis<br><br><br><br>------<br>BTW: Maybe a screenshot of the leakage<br>may help us to see what is going on....<br><br><br>--------------------------------------------------------------------<br><div class="gmail_quote">

How to segment airway from CT images?<br>
I tried ThresholdConnectedFilter, but there is always lots of leakage. As<br>
the result of leakage, many unwanted areas are included in result.<br>
<br>
Thanks<br>
