What is the primary purpose of standardized QC tests when abnormalities are detected?

• A. Designed to detect slowly evolving functional X-ray and equipment abnormalities
• B. To permit corrective action before significant deterioration of image occurs
• C. Both of the above
• D. None of the above

Answer: (C)

QC tests are designed to monitor performance over time and catch deviations from a stable baseline. Abnormalities found in standardized QC can reflect slowly evolving functional issues in the x-ray system or its components. When such abnormalities are detected, the structured QC process guides corrective actions—calibration, adjustment, or repairs—before image quality degrades noticeably. The goal is to act proactively to maintain consistent image quality and minimize unnecessary retakes and patient dose. Because this covers both detecting gradual changes and enabling timely corrections, both aspects describe the primary purpose.
