[vtkusers] select individual iso-lines

Hi,

I am using vtkContourFilter to generate the 
inner and outer perimeter contours from a
binary thresholded image of a bone cross-section.
The filter generates the closed outer bone 
surface contour and the closed marrow-bone surface
contour. Is there a way to extract each one
separately from the vtkPolyData output?
