[Insight-users] segment bones of wrist

[Luis Ibanez]

Hi Aditya,

You may want to try the sequence:

1) First, threshold the CT image at a high
    HU value (>800, for example).

2) Then, from that starting binary mask,
     use the filter

itkDownwardFrontPropagationLabelImageFilter

    that you will find in the NAMIC Sandbox

in the directory:
http://svn.na-mic.org/NAMICSandBox/trunk/VotingHoleFillFloodingImageFilter/

     You will need to define a lower HU threshold
     to stop the front propagation.


Once you have a segmentation, you can
convert the images to vtkImageData

See, for example:
http://www.insight-journal.org/browse/publication/146

whose code is now in

    InsightApplications/Auxiliary/vtk


and do surface and/or volume rendering
visualization with VTK, as illustrated in:

http://www.vtk.org/Wiki/VTK/Examples/Cxx#Volume_Rendering


     Regards,


          Luis
