Answer to Question 1

perpendicular to the humerus

Rationale: Situations of trauma elbows may present with the patient unable to fully extend the arm. Two AP projections may be acquired, one with the forearm parallel to the image receptor and the CR perpendicular to the forearm and the second with the humerus parallel to the image receptor and the CR perpendicular to the humerus. A 90 degree lateral is also taken in the most tolerable position possible.

Answer to Question 2

emulsion cracking

Rationale: The drying mechanism in automatic processing should remove the majority of moisture from the film. Excessive drying can remove all of the moisture, causing the film emulsion to crack.
