Question

an increase in which of the following technical factors would decrease patient exposure?
kilovoltage peak (kvp)
milliampere - seconds (mas)
focal spot size (fss)
filtration

Explanation:

Increasing filtration in imaging techniques absorbs low - energy photons, reducing the overall radiation reaching the patient and thus decreasing patient exposure. Increasing kVp, mAs, or focal spot size generally increases exposure or affects image quality in other ways rather than decreasing patient exposure.

Answer:

Filtration
