How does the fan beam scanner acquire data?

• A. One data point at a time
• B. All lines of data at once
• C. Column by column
• D. In segmented intervals

Answer: (B)

The fan beam scanner acquires data by capturing all lines of data at once, allowing for a more comprehensive analysis of bone density. This method utilizes a fan-shaped beam of X-rays that sweeps across the region being examined, enabling simultaneous collection of multiple data points in a single pass. This approach significantly enhances efficiency and increases the speed of the scanning process compared to methods that gather data one point or one line at a time. By acquiring data in this manner, fan beam scanners provide a more detailed and complete assessment of the bone structure, which is essential for accurate evaluation of bone mineral density.
