How do grid ratio and grid frequency affect X-ray image quality?

Grid ratio and grid frequency are crucial parameters in X-ray imaging that significantly impact image quality.

Grid ratio refers to the height of the lead strips in relation to the interspace between them. A higher grid ratio reduces scatter radiation effectively but requires higher radiation exposure to penetrate the grid, potentially leading to increased patient dose. Conversely, a lower grid ratio decreases patient dose but may not eliminate scatter effectively.

Grid frequency refers to the number of lead strips per inch or centimeter. A higher grid frequency provides better scatter cleanup, enhancing image contrast and clarity. However, it also demands higher radiation exposure due to increased attenuation. Lower grid frequencies may not be as effective in reducing scatter, resulting in degraded image quality.

Optimal selection of grid ratio and frequency is essential to balance image quality with patient radiation dose, ensuring diagnostic accuracy while minimizing radiation risks. We are a manufacturer of X-ray machines and their accessories.
