Does the dose increase as the grid density increases?
増えません。格子比を調整することが重要です。
When considering grid specifications alone, the thickness of the grid differs between a 40-wire 8:1
grid and an 80-wire 8:1 grid. Grid performance is significantly influenced by the amount of lead it contains. In a simple comparison
, the 40-wire grid is thicker, making it more difficult for primary X-rays to pass through and resulting in better scatter ray rejection.
By adjusting the
grid ratio to strike the right balance between high-contrast images and images with good transmission of primary X-rays, you can use a grid that meets your
specific performance requirements. To enhance contrast, increase the grid ratio; to improve transmission, decrease the grid ratio.
We have also developed software that simulates grid performance based on our extensive archive of shipment data. This allows you to review performance values that closely
match actual measurements without having to physically manufacture the grid, enabling you to finalize the grid specifications in a short period of time.
