If QC tests indicate issues, what is the recommended response?

• A. Ignore until the next scheduled test
• B. Implement corrective action before image quality deteriorates
• C. Replace the entire system
• D. Document and wait

Answer: (B)

Quality control tests exist to catch performance drift before it affects patient images. When a QC result shows an issue, the proper response is to implement corrective action right away to bring the equipment back into spec and prevent further degradation of image quality. This means identifying the root cause and performing the necessary maintenance or adjustments, which could include recalibration, cleaning, component repair or replacement, and any other required fixes, followed by rechecking with QC to verify the problem is resolved.

Once the equipment meets standards again, imaging can resume, and you should document what was done and the test results. If the issue cannot be resolved promptly, escalate to a supervisor or service personnel and suspend use of the affected unit until it is fixed. Ignoring the problem, waiting, or replacing the entire system without first confirming the issue is beyond repair are not appropriate initial responses because they fail to protect image quality and patient safety.
