When the optional high-level (boost) control is activated, what is the maximum tabletop dose rate when acquiring images without recording devices?

When the optional high-level (boost) control is activated during fluoroscopic imaging, the system is designed to allow higher radiation dose rates to improve image quality in certain clinical situations, such as when the standard imaging settings do not provide adequate visualization.

The correct value for the maximum tabletop dose rate during this scenario is 20 R/min. This level is established to ensure that healthcare professionals have the capability to obtain high-quality images when necessary while maintaining awareness of radiation safety standards. Knowing this maximum dose rate helps operators manage patient exposure effectively, ensuring that images can be acquired with sufficient clarity while minimizing unnecessary radiation.

The other dose rates listed are lower than what is permitted when using the boost feature. Therefore, these values do not apply in the context of high-level fluoroscopy, as the boost setting is specifically meant to exceed typical dose rates for better imaging capabilities under selected conditions. Understanding these parameters is critical for safe fluoroscopic practices.
