What is the recommended scan speed/mode for a body part thickness of 13-25 cm?

• A. Turbo Array (Hologic)
• B. Standard Mode (Lunar)
• C. Thick Mode (Lunar)
• D. Thin Mode (Lunar)

Answer: (B)

The recommended scan speed/mode for a body part thickness of 13-25 cm is Standard Mode, particularly in the context of Lunar systems. This mode is designed to optimize image quality while ensuring that the scan time is efficient for thicker body parts, such as those within the specified thickness range.

In Standard Mode, the system uses a conventional scanning technique that provides a good balance between resolution and scan speed. This is essential for ensuring accurate measurements while accommodating the increased thickness of the body part being assessed. When dealing with a thicker area, using the Standard Mode allows for sufficient data acquisition, reducing the likelihood of artifacts that could compromise the integrity of the bone density measurements.

Other modes, such as Turbo Array, Thick Mode, or Thin Mode, are optimized for different specific conditions or requirements. For instance, Turbo Array is designed for faster scans but may not be suitable for all thicknesses. Thick Mode could be suitable for very thick areas but may lead to longer scan times than necessary for a 13-25 cm thickness, and Thin Mode is meant for thinner body parts, which would not apply effectively in this range. Therefore, Standard Mode is the optimal choice for ensuring accurate evaluations within the specified thickness range.
