What is a primary purpose of standardized quality control tests performed on radiography equipment?

• A. Detect slowly evolving functional abnormalities
• B. Permit corrective action before deterioration of image quality occurs
• C. All of the above
• D. None of the above

Answer: (C)

Quality control tests on radiography equipment are about ongoing performance monitoring so imaging remains consistent and safe over time. Many faults don’t appear all at once; they drift gradually as components wear or drift from calibration. Standardized QC checks track these trends, so slowly evolving abnormalities can be detected before they noticeably affect image quality. At the same time, when a QC measurement falls outside acceptable limits, it signals that maintenance or calibration is needed before image quality deteriorates or patient dose increases due to repeat exams. Because QC serves both detecting gradual changes and triggering timely corrective action, the best choice reflects that both aspects are true.
