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.
