If you set the output voxel spacing, then you _know_ the output voxel
spacing.
And in fact VTK knows the output voxel spacing too, because it is stored
with
the vtkImageData.

You are always taking the voxel spacing into account when you are making
your measurements, aren't you?  If you do so, then all the measurements
should be accurate.
