How often should a CT machine be calibrated for optimal performance?

A CT machine should be calibrated daily to ensure optimal performance. Daily calibration helps in maintaining the accuracy and precision of the imaging system, which is crucial for diagnostic quality. This frequent calibration allows for the detection of any drift in the system’s parameters that could affect image quality or dose accuracy. Regular adjustments help in aligning the system to manufacturer specifications, ensuring reliable and consistent results over time.

While less frequent calibrations may be adequate in some scenarios, daily calibration is particularly important in a clinical setting where patient safety and diagnostic accuracy are paramount. Regular monitoring and adjustment of the CT machine's performance contribute to the overall quality assurance program in radiology, ultimately enhancing patient care and outcomes.
