Which protective feature is designed to reduce exposure to the patient during fluoroscopic procedures?

• A. Automatic collimation
• B. Protective curtain
• C. Five-minute reset timer
• D. Bucky slot cover

Answer: (A)

During fluoroscopy, limiting the beam to just the area of interest is the most direct way to protect the patient. Automatic collimation does exactly this by adjusting the field size to match the anatomy in view, so less tissue is irradiated and less scatter is produced. This beam-restriction approach directly reduces patient dose and improves image quality by reducing unnecessary exposure. Protective curtains shield staff from scatter, the five-minute reset timer mainly limits fluoroscopy time for personnel, and the bucky slot cover protects against leakage—none of these are primarily about reducing the patient’s radiation dose.
