This is not a trivial problem. It is not possible to do that given your raw contours. If you can convert your contours to a closed surface, then you can use vtkVoxelModeller to create a vtkImage. Then you can create an itk image using vtkITKImageFilter.

Alternatively, you can fit a closed geometry to your contours and create voxels based on the parameterization of your geometry: http://www.mit.edu/~adalca/files/papers/nerve_segmentation.pdf
