A less than optimal PA axial cranium projection (Caldwell method) that requires the chin to be elevated to obtain optimal positioning will
 
  a. demonstrate unequal distance from the lateral orbital margins to the lateral cranial cortices on both sides.
  b. demonstrate the superior orbital fissures within the orbits.
  c. demonstrate the petrous ridges and pyramids in the superior half of the orbits.
  d. need the IOML to be aligned perpendicular to the IR.

Question 2

An acanthioparietal facial bone projection (Waters method) with poor positioning demonstrates the petrous ridges too far inferior to the maxillary sinuses. How could the positioning setup be adjusted for an optimal projection to be obtained?
 
  1. Depress the patient's chin.
  2. Align the central ray parallel with the MML.
  3. Align the MML perpendicular to the IR.
  4. Adjust the central ray angulation caudally.
  a. 1 and 3 only
  b. 2 and 3 only
  c. 1 and 4 only
  d. 1, 2, 3, and 4
