How do focused grids differ from parallel grids in X-ray imaging?

Focused grids and parallel grids are both used in X-ray imaging to reduce scatter radiation and improve image quality, but they operate differently.

Focused grids have lead strips angled to coincide with the diverging paths of X-rays originating from the focal spot. This arrangement helps to more effectively absorb scattered radiation while allowing primary radiation to pass through, enhancing image contrast. However, focused grids are sensitive to positioning errors and have a limited range of focal distances.

On the other hand, parallel grids have lead strips oriented parallel to each other. They are effective when the X-ray source and detector are fixed in position. While they are less sensitive to alignment errors, parallel grids may not be as efficient in scatter rejection compared to focused grids.

In summary, focused grids are optimized for specific focal distances but are sensitive to alignment, while parallel grids offer more flexibility in setup but may be less effective in scatter rejection. We are a manufacturer of X-ray machines and their accessories.
