Quizplus · Accepted Answer

Grid ratio refers to the relationship between the height of the lead strips and the distance between them, and higher ratios improve contrast.

Answer: C
 Contrast improvement factor (CIF) is the measure of how much the grid improves contrast, with higher values indicating greater improvement.

Answer: D
 Focussed grids are designed to match the divergence of the x-ray beam and are more effective at reducing scatter radiation.

Answer: E
 The air-gap technique involves increasing the distance between the patient and the image receptor to reduce scatter radiation, which can improve contrast.

Answer: G
 Grid cut-off occurs when the lead strips of a grid absorb too many of the primary x-rays, resulting in decreased image quality.

Answer: J
 Gustav Bucky was a physicist who helped develop the first grid in 1913.
