title: New exposure indicators for digital radiography simplified for radiologists and technologists.
abstract: OBJECTIVE
  The purpose of this article is to educate radiologists and technologists about the clinically relevant portion of the new digital radiography standards.
  
  
  CONCLUSIONS
  Both the International Electrotechnical Commission (IEC standard 62494-1) and the American Association of Physicists in Medicine (AAPM Task Group 116) have developed similar standards for monitoring exposure in digital radiography to eliminate proprietary and confusing terminology. Radiologists and technologists will need to learn three new terms--exposure index, target exposure index, and deviation index--to understand the new standards.
