What are the options for the grid purchase?

The grid is no stranger to many hospital dealers. The grid is mainly used on chest racks, photographic flat beds and other medical X-ray machines, but many people don’t know that different models need to be customized with different sizes of grids. But what is the grid?

(1) focal length range

   From standard short focus (26″-32″) focal length (34″-44″) far focus (40″-72″, 48″-72″ 60″-72″) until infinity (parallel line). The focal lengths commonly used in medical applications are mainly 100 cm, 130 cm, and 180 cm.

(2) High gate density

From 60 or 70 lines/inch to high density (85 lines/inch), ultra high density (103 lines/inch), invisible line (105 lines/inch), super invisible line (170 or 200 lines/inch) . Commonly used grid densities are 85 lines/inch and 103 lines/inch.
