The distance from the anterior nasal spine to the lateral soft tissue on both sides is equal on a tangential (superoinferior) nasal bones projection when the
 
  a. GAL is aligned perpendicular to the IR.
  b. midsagittal plane is aligned perpendicular to the IR.
  c. central ray is angled caudally.
  d. patient is placed in a prone position.

Question 2

An acanthioparietal sinus projection (Waters method) can be distinguished from a parietoacanthi-al sinus projection because
 
  1. it demonstrates the bony nasal septum in alignment with the collimated field's longitudinal axis.
  2. it demonstrates greater orbital magnification.
  3. it demonstrates less distance from the lateral orbital rims to the lateral cranial cortices.
  4. the petrous ridges are demonstrated superior to the maxillary sinuses.
  a. 1, 2, and 3 only
  b. 2 and 3 only
  c. 1 and 4 only
