Which device is suspended above the beam defining system to reduce scatter radiation and provide gonadal protection?

The shadow shield is designed specifically to minimize scatter radiation by being positioned above the beam defining system. Its unique configuration allows it to cast a shadow over the target area, thus reducing the amount of radiation that reaches sensitive organs, particularly the gonads. By effectively blocking scatter radiation, the shadow shield provides targeted protection while allowing the primary beam to be directed where it is needed for imaging or therapeutic purposes.

In addition to its functionality in reducing scatter radiation, the shadow shield can be positioned in such a way that it does not interfere with the clinical procedure being performed. This is particularly advantageous during imaging and can enhance patient safety by lowering their overall exposure to radiation, especially to reproductive tissues.

Other devices like flat contact shields and protective aprons serve different purposes or are placed in different configurations. While flat contact shields are used for direct contact with the skin, protective aprons cover larger areas of the body, and lead curtains usually provide a barrier in a fixed position to protect against scatter. However, none serve the dual purpose of being suspended directly above the beam in the same manner as a shadow shield does.
