1. • Better scatter radiation reduction

     • A higher grid ratio leads to better scatter radiation reduction because it has narrower lead strips. The narrow lead strips absorb and block a higher percentage of scattered radiation, preventing it from reaching the detector. This results in a cleaner image with less scatter and improved overall image quality.

   How does grid ratio affect X-ray image quality?

   • An increase in the grid ratio will make the grid more effective at reducing scatter, but will also require higher x-ray tube technique. X-ray scatter due to Compton Scatter generates background haze in x-ray images and there is a desire to reduce the scatter impact on image quality.

   How X-ray images are acquired using a grid in a digital radiography system?

   • Figure 1 presents the overall system for acquiring X-ray images using a grid in a digital radiography (DR) system. A grid is placed between the detector and subject, and it contributes to increasing the diagnostic accuracy by removing scattered radiation [2, 3, 4].

   Why is a grid important in a digital radiography system?

   • A grid is one of the key components of a digital radiography (DR) system because it removes scattered radiation, which arises when X-rays penetrate an object and improves diagnostic accuracy by enhancing image quality. With the widespread use of DR systems, demand for grids with high precision has simultaneously increased.

   How does a grid affect a radiograph?

   • The absence of scattered radiation on an image produced with a grid reduces the exposure to the image receptor when compared to an image produced without a grid. Also, when a radiograph is taken with a grid, the lead in the grid will absorb some primary radiation, even when it is being used correctly.

   What causes grid cut-off in X rays?

   • Grid cut-off also occurs if the x-ray tube is straight but the grid is at an angle. This causes the x-ray beam to be directed against the grid lines. This problem can occur in clinical practice during portable radiography when the patient is lying on an image receptor with a grid on top of it.

   Does removing a grid improve image quality?

   • Therefore, image quality is instead quantified by signal-difference-to-noise ratio (SDNR), a.k.a. contrast-to-noise ratio (CNR). Removing the grid allows more primary radiation to reach the detector, which might compensate for the additional quantum noise caused by scattered radiation. If so, using a grid is not beneficial.

   Incorrect centering of the x-ray beam to the center line of the grid can cause grid cut-off on the radiograph. The x-ray tube should always be positioned so that the central ray is pointed at the center line on the grid.

   The grid ratio is the ratio of the height of the grid plate, often called grid septa, to the separation width (grid Ratio = h/D). If the width of the grid plates is left constant then higher grid plates will block more scatter.
