1.41). A radiographic examination involves five general functions:

A
  1. Positioning of body part and alignment with the IR and CR
  2. Application of radiation protection measures and devices
  3. Selection of exposure factors (radiographic technique)
  4. Instructions to the patient related to respiration (breathing) and initiation of the x-ray exposure
  5. Processing of the IR (analog) [chemical processing] or digital processing systems
