How often must ultrasound equipment be calibrated?

• A. Calibrated once a year
• B. Calibrated every six months
• C. Calibrated every two years
• D. Calibrated monthly

Answer: (A)

Regular maintenance and calibration of ultrasound equipment is essential to ensure accurate energy delivery and patient safety. Calibrating the device once a year, by a qualified service technician, is the standard practice because it verifies that output intensity, frequency, and beam characteristics remain within specified tolerances over time. This annual check helps ensure that treatments are delivering the intended dose, which is crucial for effectiveness and safety. Between calibrations, clinicians typically perform routine daily or per-use output checks to screen for drift or malfunction, but a formal calibration is commonly done annually. Calibrating every six months or monthly is more frequent than usually required and can be unnecessary unless the device shows signs of drift or is used in high-demand settings. Waiting two years between calibrations increases the risk of undetected changes in performance.
