A poorly positioned parietoacanthial facial bone projection (Waters method) demonstrates the petrous ridges within the maxillary sinuses. How was the positioning setup mispositioned for such a projection to be obtained?
 
  1. The MML was not aligned perpendicular to the IR.
  2. The patient's head was rotated toward the left side.
  3. The patient's chin was tucked more than needed.
  4. The central ray was angled too cephalically.
  a. 1 and 3 only
  b. 2 only
  c. 3 and 4 only
  d. 1, 3, and 4 only
