DUNLEE Fiber interspaced grids


A grid has two major roles:


1. Using its lamellae, to absorb as much scatter as possible in order to improve the image quality

2. Using its interspacer, to transmit primary X-rays


Fiber‘s high transparency makes it the perfect interspacer material. Indeed, it loses 20% - 40% less primary radiation, which is important for picture quality, than conventional aluminum interspacer material.

Smit Röntgen is the only supplier able to deliver fiber-interspaced grids in high volumes. 


  • On average, 20% - 40% less primary radiation is absorbed


  • Dose is verifiably lower as compared with aluminum interspaced grids
