Hi David,

Check out this example:

http://www.itk.org/Wiki/ITK/Examples/Iterators/ImageRegionIterator

You'll want to modify the iterator loop to look like:
  while(!imageIterator.IsAtEnd())
    {
    if(imageIterator.GetIndex()[0] > 10)
      {
      imageIterator.Set(0);
      }
    ++imageIterator;
    }
