QA checks on radiographic equipment should be performed how often?

• A. Weekly checks
• B. Biannual checks
• C. Daily processing checks, monthly constancy checks, and annual safety inspections
• D. Quarterly

Answer: (C)

Regular QA of radiographic equipment uses a tiered approach to catch problems at different time scales. Daily processing checks verify the film development system is functioning correctly, ensuring the processed radiographs have acceptable density and contrast. Monthly constancy checks assess that the x-ray unit’s output remains consistent from day to day, guarding against gradual changes in generator output or film-response. Annual safety inspections review shielding, interlocks, exposure control accuracy, and overall safety compliance. This combination—daily processing, monthly constancy, and annual safety inspections—best covers both image quality and patient safety over time.
