Contrast And Spatial Resolution Practice Test

When choosing between two radiographic grids, the grid with the higher K factor results in

lower scatter no change decreased scatter a higher degree of scatter and secondary radiation clean-up

Correct Answer:

a higher degree of scatter and secondary radiation clean-up

Explanation:

Higher K factor means the grid is more effective at removing scattered radiation, which lowers the amount of scatter that reaches the image receptor and thereby improves image contrast. The K factor (contrast improvement factor) reflects how much the grid enhances contrast by absorbing secondary radiation; a higher value indicates greater cleanup of scatter. This doesn’t increase scatter; it reduces it. Keep in mind, using a grid with a higher K factor also means more primary photons are absorbed by the grid, so you typically need to increase exposure to maintain the same receptor density.
