What represents a standard practice in the calibration of DXA machines?

• A. Weekly calibration checks
• B. Daily performance assessments
• C. Annual external audits
• D. Monthly internal reviews

Answer: (B)

Daily performance assessments are essential in the calibration of DXA machines because they ensure that the equipment is functioning accurately and providing reliable measurements for bone density. By performing these assessments each day, technicians can quickly identify any deviations in the machine's performance or accuracy. This frequent monitoring is crucial, as it helps in maintaining the integrity of the results, which directly impacts patient care and diagnosis. Daily performance checks typically involve evaluating the calibration of the machine using a known standard or phantom to ensure consistency and precision. This practice is part of quality assurance protocols that help detect any issues that may arise from environmental factors, such as temperature changes or equipment wear and tear, thereby ensuring the machine operates within the accepted performance limits. Regular performance assessments help to uphold the reliability of the bone density measurements that the DXA machines are designed to provide. Other options, while relevant to maintaining the overall quality and safety of medical imaging equipment, do not emphasize the daily frequency that is critical for immediate response to possible calibration drift or operational issues.
