What are the characteristics of a 16:1 grid?

A 16:1 grid is designed to optimize the imaging quality by reducing the amount of scattered radiation that reaches the imaging receptor. This type of grid does indeed absorb a high percentage of scattered radiation, which helps improve image contrast and clarity. The ratio indicates that for every 16 units of height of lead strips, there is a 1 unit space in between. This significant lead content enhances its ability to absorb scatter.

In terms of positioning latitude, a grid with this high ratio tends to have little positioning latitude. This means that there is a relatively narrow margin for error regarding how the grid must be aligned with the X-ray beam. Any misalignment can lead to grid cut-off, where parts of the image become underexposed due to excessive absorption of the useful radiation.

A 16:1 grid is also typically used with high-kVp exposures, where the penetration power of the X-ray beam is considerably higher. High kilovolt peak settings increase the energy of the X-ray photons, and the 16:1 ratio is suitable for these situations because it is efficient at attenuating the scatter while still allowing the primary beam to pass through effectively.

Therefore, all the listed characteristics accurately describe a 16:1 grid, making the option encompassing
