Answer to Question 1

arm is abducted 90 degrees from the body

Rationale: Scapula imaging can be performed upright or supine. The arm must be abducted 90 degrees from the side of the body in order to pull the axillary (lateral) border of the scapula and a portion of the scapula free of superimposition of the ribs. In addition, it will help flatten the scapula; it will be positioned more parallel to the plane of the image receptor.

Answer to Question 2

15 rem

Rationale: The annual dose limit for a radiographer to the lens of the eye should be 15 rem or 150 mSv or less.
