Artefacts found in computed radiography

Artefacts on radiographic images are distracting and may compromise accurat e diagnosis. Although most artefacts that occur in conventional radiography have become familiar, computed radiography (CR) systems produce artefacts that differ from those found in conventional radiography. We have encounter ed a variety of artefacts in CR images that were produced from four differe nt models plate reader. These artefacts have been identified and traced to the imaging plate, plate reader, image processing software or laser printer or to operator error. Understanding the potential sources of CR artefacts will aid in identifying and resolving problems quickly and help prevent fut ure occurrences.
