How often are radiographic equipment calibrations performed under QA?

Radiographic equipment calibration is part of ongoing QA to keep image quality and patient safety consistent. Because equipment performance can drift over time due to wear, heat, or changes in the environment, calibrations are performed at defined intervals set by the QA program—often monthly or quarterly. This regular schedule helps verify that the output exposure, timer accuracy, beam quality (HVL), reproducibility, and alignment remain within acceptable limits, and it allows for timely adjustments if any drift is detected. Doing it only at installation would miss later changes, and never calibrating would be unsafe. Calibrating only yearly may miss significant drift that can affect dose and image quality. So, the defined-interval approach best ensures reliable performance and safety.
