[Diane]

The posterior surfaces of the vertebral bodies are demonstrated without superimposition on a left lateral lumbar vertebrae projection.
 
  The most magnified ribs are demonstrated posteriorly. How should the positioning setup be ad-justed to obtain an optimal projection?
  a. Rotate the side positioned farthest from the IR posteriorly until the midsagittal plane is perpendicular to the IR.
  b. Rotate the right side anteriorly until the midcoronal plane is perpendicular to the IR.
  c. Rotate the patient until the midsagittal plane is perpendicular to the IR.
  d. Align the midsagittal plane parallel with the IR.

Question 2

For a lateral coccygeal projection,
 
  1. the longitudinally and transversely collimated fields can be closed to a 4-inch (10-cm) field size.
  2. the posterior ribs and the posterior pelvic wings are positioned perpendicular to the imaging table.
  3. the patient's legs are extended.
  4. a small focal spot improves recorded detail sharpness.
  a. 1 and 4 only
  b. 2 and 3 only
  c. 1, 2, and 4 only
  d. 1, 2, 3, and 4
