Quality assurance and maintenance of CR cassettes include cleaning and inspecting the plates at least:

• A. Daily
• B. Every 48 hours
• C. Every 3 months
• D. Weekly

Answer: (D)

Regular maintenance of CR cassettes centers on keeping the imaging plate clean and intact so that artifacts don’t show up in images and image quality stays consistent. Dust, fingerprints, and residues on the plate can create background fog or small spots, degrading contrast and making subtle details harder to see. Scratches or cracks in the plate or cassette housing can compromise sharpness or allow light leaks, which also harms image quality. Cleaning and inspecting at least weekly provides a practical balance: it’s frequent enough to catch accumulating contaminants and emerging damage before they affect many studies, but not so frequent that it becomes an unnecessary burden in a typical clinical workflow. Daily cleaning would be overkill in many settings, and waiting months could let artifacts go unnoticed. In busier or dustier environments, more frequent checks may be warranted, but weekly remains a solid standard for maintaining reliable QA in CR cassettes.
