Which combination of QC test records must be maintained?

• A. 1 only
• B. 2 only
• C. 1 and 2
• D. 1, 2, and 3

Answer: (D)

Maintaining a complete set of QC test records across all required categories is essential because it provides a full, verifiable history of equipment performance. Each type of record serves a different purpose and together they support confidence in image quality and patient safety.

Baseline acceptance records show the equipment met specifications when installed or after major service, establishing a starting point for performance. Routine QC records document ongoing performance over time, helping to detect drift or deterioration before it affects image quality or dose. Maintenance and calibration or repair records explain what actions were taken, when, and by whom, so anyone reviewing the history can understand how issues were addressed and whether performance was restored to spec.

Regulatory and accreditation bodies require retention of these records for a defined period, and having all three categories ensures you can demonstrate compliance, conduct effective trend analysis, and respond to any inquiries or investigations with a complete performance history.
