A radiograph of a posteroanterior (PA) axial projection (Caldwell method) of the cranium reveals that the petrous ridges are located within the level of the lower one third of the orbits. The technologist performed this projection with the CR angled 15° caudal to the orbitomeatal line (OML). Is repositioning needed; if so what should be altered if a repeat exposure is performed?

A patient comes to radiology for a routine study of the cranium.  They are unable to flex their head and neck sufficiently to place the OML perpendicular to the IR for the AP axial Townes projection. What should the technologist do to compensate for this problem without creating excessive magnification of the occipital bone?
