In diagnostic imaging, shielding primarily reduces exposure to which of the following?

• A. The patient’s exposed organs.
• B. The operator and nearby staff.
• C. Image resolution.
• D. Equipment cost.

Answer: (B)

Shielding in diagnostic imaging is all about protecting people in the room from radiation by attenuating scatter that comes from the patient after the primary beam passes through. This scatter is what exposes anyone nearby as the patient is positioned and exposed. The people most at risk are the operator and other staff who stand close to the table during imaging, so protective barriers and lead apparel are used to reduce their received dose. Shielding doesn’t directly change image resolution, nor does it affect the cost of the imaging equipment; those factors are related to technique, detector quality, and system design rather than shielding.
