Digital radiography has largely replaced film-screen radiography in medical practices in the United States, and continues to drive increased growth of radiography services worldwide. Clinical practice guidelines and best practices have been developed for radiographers and other imaging professionals to ensure that optimal image quality is attained using the minimum appropriate radiation dose for every digital radiograph. These guidelines make practical and specific recommendations for many aspects of the digital radiography process, including image acquisition, the use of radiation dose indicators, image processing and display, and data storage and transmission. Digital processing makes it possible to obtain diagnostic images even with radiation exposure levels that would result in overexposure or underexposure with film-based radiography. However, quality control remains an essential part of digital radiography, and requires a continual process of image analysis, review of rejected images, and assessment of artifacts. The radiographer works closely with radiologists, medical physicists, and other professionals to ensure the accuracy and safety of digital radiography systems under their care.
After reading this article, the participant should be able to:
- List best practices and guideline recommendations to improve image acquisition in digital radiography.
- Identify factors that contribute to diminished image quality.
- Describe best practices for conducting rejected/repeated image analysis.
