Answer to Question 1

in the film bin

Rationale: Opened boxes of film should be stored within the film bin, a light proof source of storage.

Answer to Question 2

40 degrees

Rationale: The Merchant method is a bilateral method to image the patella in profile and the patellofemoral joints. The legs must be relaxed and flexed approximately 40 degrees off the end of the table. The beam is directed superior to inferior to pass through the patellofemoral joint space.
