Which elements are included in x-ray equipment performance evaluation as part of QC testing?

• A. Acceptance testing
• B. Radiation safety surveys
• C. Both acceptance testing and safety surveys
• D. None

Answer: (C)

Evaluating x-ray equipment performance in QC involves two integrated activities: acceptance testing and radiation safety surveys. Acceptance testing is done when equipment is installed or after major service to confirm the unit meets the manufacturer’s specifications and performance criteria, such as accurate kVp, timer accuracy, mA linearity, image geometry, and reproducibility. Radiation safety surveys assess the safety side of operation, checking leakage radiation, shielding integrity, exposure rates, and the proper functioning of safety features like interlocks, collimator accuracy, and exposure controls. Together, these ensure the machine delivers the expected image quality while protecting patients and staff, so both elements are included in a complete performance evaluation. Limiting to only one aspect would miss either performance fidelity or safety compliance.
