Question

Which of the following will result if magnification is used in a 20/9/6 inch image intensifier?

1) Spatial resolution improves
2) Patient dose increases
3) Focal point shifts closer to the output phosphor

Answer 1

Using magnification in a 20/9/6 inch image intensifier will improve spatial resolution, increase patient dose, and shift the focal point closer to the output phosphor.

Step-by-step explanation:

Magnification is the ratio of the near-point distance to the focal length of the magnifying lens. Using a lens with a shorter focal length will result in a stronger magnification. In the case of a 20/9/6 inch image intensifier, using magnification will improve spatial resolution, increase patient dose, and shift the focal point closer to the output phosphor.
