Which shielding device is typically used in the operating room to cover the region of interest without contacting the patient?

• A. Shadow shield
• B. Contact shield
• C. Ceiling shield
• D. Wall shield

Answer: (A)

Selective shielding in the OR aims to block scatter from reaching tissues outside the area being imaged while keeping the region of interest exposed. The shield that fits this need is designed to be positioned so it casts a protective shadow exactly over the region of interest without touching the patient. This shadow shield is typically suspended or mounted on a stand and aligned to the ROI, allowing precise shielding of surrounding tissues while the patient remains untouched and the sterile field intact. It can be moved easily as the imaging field changes during the procedure, which helps maintain image quality while reducing unnecessary dose. A shield that must contact the patient is not suitable here, since the requirement is no contact with the patient. Other shields, like those mounted on the ceiling or on a wall, provide broad protection but are not as precisely targeted to the ROI without touching the patient, making the shadow shield the best choice for this scenario.
