Which of the following controlling factors will most affect radiographic resolution?

Question

Quizplus · Accepted Answer

Focal spot size is the controlling factor that affects radiographic resolution the most. A smaller focal spot size produces a sharper image with greater detail and better resolution, while a larger focal spot size produces a less sharp image with lower detail and lower resolution. Therefore, it is necessary to select the smallest possible focal spot size that can provide adequate radiation output for the examination. The other factors listed, such as kV, mAs, and filtration, can also affect radiographic quality, but they do not have as direct an impact on resolution as focal spot size.
