Answer to Question 1

angle the central ray 5 degrees caudal

Rationale: If the L5-S1 disk space is closed as evidenced on the lateral lumbar projection, a 5-7 degree caudal tube angle should be applied to direct the beam parallel to this disk space.

Answer to Question 2

alerts the occupational worker of the length of time live radiation has been produced

Rationale: The cumulative timer for image intensification or fluoroscopy will alert audibly every 5 minutes and then be required to be reset. This timer helps to remind occupational workers of the radiation time and must be recorded for patient exams.
