Question

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

Explanation:

In medical imaging, increasing filtration removes low - energy photons that contribute little to image quality but increase patient exposure. Increasing kVp, mAs, or focal spot size generally does not decrease patient exposure. Increasing kVp can increase penetration but also scatter. Increasing mAs increases the radiation dose. Focal spot size mainly affects image sharpness and not exposure in a way that decreasing exposure.

Answer:

Filtration
