Which shield is described as suspended over the region of interest?

• A. Shadow shield
• B. Contact shield
• C. Table shield
• D. Chair shield

Answer: (A)

The main idea here is how shielding is positioned to protect tissue without interfering with the image. An overhead shield is suspended above the region of interest, not touching the patient, so it can block scatter and protect surrounding tissues while leaving the area you want to image clear. This setup creates a “shadow” over the patient in the radiograph, which is why it’s called a shadow shield. It’s ideal when you need to shield sensitive areas like gonads or breasts without placing anything in contact with the patient or directly in the beam path. Other shields are mounted differently: a shield that sits on the patient, a shield that sits on the table, or one attached to a chair. These are not described as being suspended overhead, which is why the overhead shadow shield best fits the description in the question.
