Shuttering the digital image will reduce the exposure to the patient.

• A. True
• B. False
• C. It depends on the device
• D. Only for film-based systems

Answer: (B)

Shuttering the digital image does not change the radiation that reaches the patient. The dose is determined by the X-ray beam's exposure factors (kVp, mA, exposure time, filtration, and beam collimation). Shuttering only stops the detector from recording or displaying the image; it does not reduce the amount of radiation produced or delivered during the exposure. To lower patient dose, you need to adjust exposure factors, use proper collimation, shielding, and other dose-saving practices.
