Question

In order to maintain the same fluoroscopic screen brightness, patient dose can be reduced if:

1. the image intensifier is positioned as far away as possible from the patient
2. the target-to-skin distance is increased
3. is not possible
4. the target-to-skin distance is decreased

Answer 1

To maintain the same fluoroscopic screen brightness, patient dose can be reduced by increasing the target-to-skin distance. Therefore, option 2, increasing the target-to-skin distance, is the correct answer.

Step-by-step explanation:

To maintain the same fluoroscopic screen brightness, patient dose can be reduced by increasing the target-to-skin distance. When the target-to-skin distance is increased, the radiation spreads out more, resulting in a smaller dose received by the patient. This is because the radiation intensity drops inversely proportional to the square of the distance.
