The purpose of this article is to educate radiologists and technologists about the clinically relevant portion of the new digital radiography standards.
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.
本文旨在向放射科医生和技师介绍新的数字放射摄影标准中与临床相关的部分。
国际电工委员会 (IEC 标准 62494-1) 和美国医学物理学家协会 (AAPM 工作组 116) 都制定了类似的数字放射摄影曝光监测标准，以消除专有和混淆的术语。放射科医生和技师需要学习三个新术语——曝光指数、目标曝光指数和偏差指数——才能理解新标准。
