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) Variable size

   From the standard 5″ x 7″ to 14″ x 51″, the special size can also be customized according to customer requirements, the size of the grid is one inch larger than the corresponding film size. The more common size is 15″ x 18″.

(2) Variable gate ratio

   From 3:1 to 15:1, the gate ratio refers to the ratio of the height of the lead grid strip to the width of the gap. The more commonly used raster ratios are 8:1, 10:1, 12:1.

(3) focal length range
