Choosing the Right Grid and Grid Encasement

Because image quality can be greatly affected by the choice of grid, choosing the correct specifications is very important. The following information is needed when choosing a grid/grid encasement: Size, Ratio, Line Count, and Focal Distance.

Size: AliMed offers five sizes of grids. In addition, grids from 5" x 7" up to 15" x 51" in multiple shapes and configurations can be special-ordered.

Ratio: The relationship of the height of the lead strip to the distance between the lead strips. The higher the ratio, the more effective the grid (note that higher ratios require higher exposure rates). AliMed offers four ratios: 6:1, 8:1, 10:1, and 12:1.

Line Count: The number of X-ray-absorbing strips per inch, measured as Lines Per Inch (LPI). 103 LPI is best for analog, 178 is best for CR, while 200 is best for DR—AliMed offers these LPIs standard, and 215 and 230 LPI are available by special order.

Focal Distance: Depending on the type of X-ray exam, different focal distances are required. Focal distance is the perpendicular distance between the grid and its convergent point/line. Three focal distances are available: Short (26"-32"), Medium (34"-44"), and Long (40"-72").

What are Grid Encasements?
AliMed offers two styles of grid encasements to protect valuable X-ray grids and allow for convenient handling and operation. In addition to protecting X-ray grids, grid encasements convert cassettes into grid cassettes.
