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?

Given the image below was taken in the AC radiography lab using Bucky 1 and the CR plates (what you are acustomed to using in Mrs. Geist’s labs) 7 mAs and 80 kV with a s value # reading of 725 — which technical factors would bring the repeat exposure into optimal range?
