To ensure mechanical safety during a DXA scan, what is one important consideration?

• A. Ensure the patient is fasting
• B. Have a dedicated powerline to the scanner
• C. Limit the scan duration to 5 minutes
• D. Use only battery-operated devices

Answer: (B)

In the context of ensuring mechanical safety during a DXA (dual-energy X-ray absorptiometry) scan, having a dedicated powerline to the scanner is crucial. This consideration ensures that the DXA machine receives a stable and constant power supply, which is essential for its optimal functioning and accuracy. Fluctuations in power can lead to faulty scans, inconsistent results, and potentially compromise patient safety during the scanning process.

A dedicated power source minimizes the risk of electrical interference and helps maintain the integrity of the data collected by the scanner. This is especially important since DXA technology relies on precise energy levels to differentiate between various types of body tissues during bone density measurements. In contrast, the other options, while related to patient care or operational efficiency, do not directly address the mechanical safety and integrity of the scanning process.
