Which components does a DXA workstation typically include?

The correct answer encompasses the essential components needed for the functioning and operation of a DXA (dual-energy X-ray absorptiometry) workstation. A DXA system's display monitor and computer are crucial for the analysis and interpretation of the bone density data collected by the scanner.

The display monitor allows technologists and clinicians to visualize the images produced and the results generated from the scan, while the computer processes the data and controls the overall functionality of the DXA machine. This includes managing the scan protocols, storing patient data, and generating reports for clinical use.

Other components, while important for the operation of a complete DXA system, serve specific purposes. For instance, the scanner and positioning equipment are essential for obtaining accurate measurements but do not encompass the full range of functionalities that the computer and monitor provide for data interpretation. Similarly, a power module and cooling system, while necessary for operation, do not relate directly to the user interface or data management aspects that are essential in a clinical setting. Lastly, while a scanner and data storage are integral parts of a DXA setup, the role of the computer and display in processing and presenting results makes them a more defining pair for a workstation.
