[Insight-users] image marching cubes

[Prashanth]

All,
   I have a MR image volume of a brain with a tumor in it and 'am trying 
to extract the surfaces of the brain and the tumor using Marching Cubes. 
I would really appreciate it if someone can help me with these questions:
      (i) Can I extract the surfaces of brain AND tumor at the same time 
using Marching Cubes ? In other words, extracting two isosurfaces with 
two different contour values (one for brain and the other for tumor) at 
the same time using Marching Cubes.
      (ii) Can ITK handle this ?

Thanks
Prashanth
