标准滤线栅便于形成在收集边缘提供高磁场和高梯度的要素，压降较低。
Standard grids have advantageously shaped elements to provide high magnetic field and gradient near collecting edges, while causing very low pressure drop.
结论：考虑病人的吸收剂量和避免影像失真，摄影焦-片距的选择应与滤线栅的焦距相匹配。
Conclusion: Considering the absorbed dose of the patients and avoiding the image distortion, it is suggested that the selection of focus-film distance should be matched with the tube and grid.
在已经通过选择性激光烧结建造出结构元件之后，所述滤线栅可以是通过模塑或研磨技术无法实现的高度复杂的3d结构。
Having a structural element that is built by selective laser sintering, the grid can be a highly complex 3d structure that is not achievable by molding or milling techniques.
