Of the following grid specifications, which one is most significant in determining contrast improvement?

Question

Quizplus · Accepted Answer

Grid ratio is the most significant specification in determining contrast improvement. It measures the relation between the height of the lead strips and the distance between them. Higher grid ratios result in better contrast improvement by reducing scatter radiation and increasing the signal-to-noise ratio. Grid frequency, grid radius, and focal range also affect contrast improvement but to a lesser extent. Grid alignment is important for accurate positioning but does not directly impact contrast improvement.
