Hi Aditya,<br><br>You may want to try the sequence:<br><br>1) First, threshold the CT image at a high<br> HU value (>800, for example).<br><br>2) Then, from that starting binary mask,<br> use the filter<br><br>itkDownwardFrontPropagationLabelImageFilter<br>
<br> that you will find in the NAMIC Sandbox<br><br>in the directory:<br><a href="http://svn.na-mic.org/NAMICSandBox/trunk/VotingHoleFillFloodingImageFilter/">http://svn.na-mic.org/NAMICSandBox/trunk/VotingHoleFillFloodingImageFilter/</a><br>
<br> You will need to define a lower HU threshold<br> to stop the front propagation.<br><br><br>Once you have a segmentation, you can <br>convert the images to vtkImageData<br><br>See, for example:<br><a href="http://www.insight-journal.org/browse/publication/146">http://www.insight-journal.org/browse/publication/146</a><br>
<br>whose code is now in <br><br> InsightApplications/Auxiliary/vtk<br><br><br>and do surface and/or volume rendering <br>visualization with VTK, as illustrated in:<br><br><a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx#Volume_Rendering">http://www.vtk.org/Wiki/VTK/Examples/Cxx#Volume_Rendering</a><br>
