Quality control measurements for the accuracy of a CT scanner's calibration should be performed how often?

Quality control measurements for the accuracy of a CT scanner's calibration should be performed daily to ensure optimal performance and safety. Daily checks help to identify any variations or drifts in the scanner's calibration that could affect image quality or patient care. Regular daily assessments are critical especially because CT scans involve high levels of radiation; any inaccuracies in calibration can lead to incorrect dose delivery to patients, potentially resulting in too much exposure or inadequate imaging quality, which could hinder diagnostic accuracy.

Unlike longer intervals such as weekly, monthly, or yearly, which may not catch issues in a timely manner, daily checks allow technologists to promptly address any calibration problems. This frequent monitoring aligns with best practices for quality assurance in imaging facilities, ensuring compliance with safety standards and enhancing the overall quality of care provided to patients.
