What should be done if a bone densitometry unit is relocated?

• A. Replace all worn components
• B. Recalibrate it
• C. Test the unit with phantom scans only
• D. Inspect for any visual damages

Answer: (B)

When a bone densitometry unit is relocated, recalibrating the unit is essential to ensure accurate assessments of bone density. Relocation can alter the positioning and alignment of the equipment, which may impact its performance and the reliability of the results it generates. During the calibration process, the system is adjusted to correct for any shifts or changes that might have occurred due to the move, thereby safeguarding the accuracy and consistency of measurements.

While checking for visual damages is important to ensure that physical components are intact, and testing with phantom scans can help check for operational status, neither of those steps effectively addresses the need for recalibration. Replacing components may also be necessary depending on their condition, but this is not a direct requirement following relocation. Only recalibration ensures that the unit operates based on standardized measurements and continues to provide clinically relevant results.
