The first is the image orientation, in order to orient each volume at the same position.

Further confirmation comes from the comparison with the two-dimensional superimposition. The final result is not completed because it cannot be used to quantify the extent of growth or displacement induced by treatment. The comparison with the two-dimensional superimposition has also highlighted the limitations of the conventional teleradiography and the great advantage of the CBCT. The teleradiography has some basical errors that do not permit an accurate and unique landmarks localitazion.
