Quality assurance and maintenance of CR cassettes include erasing plates at least:

Explanation:
In computed radiography, the plate stores energy after exposure in a photostimulable phosphor layer. If the plate isn’t erased before the next exam, residual latent images can appear as ghosting on new images, degrading image quality and masking changes in detector response that QA relies on. Erasing the plate resets it to a blank state, ensuring a consistent starting point for every exposure and making it possible to accurately assess panel performance and image quality. Because ghosting can affect diagnostic quality and QA measurements, erasing should be done at least daily. Less frequent erasure risks carryover images and compromised QA results.
