The result of an AP axial clavicle with a 20 degree cephalic angle still shows too much superimposition of the medial clavicle on the rib cage. What is the next step?
 
 the tube angled should be lessened
  the tube angle should be increased to a maximum of 30 degrees
  no change needed; the image was acquired with maximum cephalic tube angle
  the tube angle should be increased to a maximum of 40 degrees

Answer to Question 1

base

Rationale: The base of the lung rests on top of the diaphragm. The costophrenic angle is formed by the base of the lung where it meets the outer margin of the cavity.

Answer to Question 2

the tube angle should be increased to a maximum of 30 degrees

Rationale: The cephalic tube angle range for the AP axial is 15-30 degrees. A more hypersthenic patient would use the lesser value in the range and an asthenic patient would use the greater value within the range.
