The open end of the PID should almost touch the face with its midpoint centered over the point of entry before exposure
Indicate whether the statement is true or false
TRUE
Explanation: The open end of the PID should be placed as close to the patient's skin as possible without touching. Failure to bring the end of the PID in close to the patient will result in an underexposed radiograph because as the beam of radiation spreads out, less radiation is available to strike the image receptor and produce a diagnostic-quality image.
