Answer to Question 1

a secondary barrier

Rationale: The x-ray tube should not be able to be directed at the control booth area. The control booth area is constructed as a secondary barrier with the lead glass window containing 1.5 mm lead equivalent.

Answer to Question 2

Coyle method

Rationale: The Coyle method is a specialty projection that can be used alternatively if a patient cannot fully extend the arm for an AP oblique with internal rotation. The Coyle method will allow the patient to flex the elbow 80 degrees, the hand remains pronated, and the central ray is angled 45 degrees from the shoulder to enter the mid elbow joint.
