[Insight-users] Creating an approximate cross-section of a RT ROI‏

[Luis Ibanez]

Hi Xiaofeng,


You should look at the filter

           itkPolylineMaskImageFilter.h

and the filter

           itkPolylineMask2DImageFilter.h


These filters will rasterize a polyline into
a binary image.

If you do this in a 3D image, then you will
have automatically the profile of this
segmented object in the orthogonal directions.


    Regards,


          Luis
