Which of the following are components of a DXA system?

A DXA (Dual-energy X-ray Absorptiometry) system is a specialized piece of equipment used to measure bone mineral density and assess osteoporosis and related conditions. The components of a DXA system are critical for ensuring accurate measurements and include a variety of essential elements for functionality and performance.

The selection identifying the workstation unit and phantom is correct because the workstation unit is the central part of the DXA system where data is processed, analyzed, and displayed. This unit typically contains the software and interface that healthcare professionals use to input patient data, control the scanning process, and interpret the results. The phantom, on the other hand, is a standardized test object that resembles human bone and is used for calibration and quality assurance of the DXA system. Regular use of a phantom helps ensure that the system provides accurate and reliable measurements over time.

The other options each mention components that either do not encompass the essential aspects of a DXA system or are too limited in scope. A display monitor and printer are peripheral devices that assist in displaying and printing results but do not represent core components of the DXA system itself. The energy switching system and cooling fan, while potentially present in some imaging systems, are not specific to the functionality needed for bone density measurements. Lastly
