The function of the x-ray filter grid filters out the messy scattered rays through the function of the lead strips, and retains the effect of direct rays to improve the quality of the film. It is generally recommended that the chest X-ray frame or the film-taking bed of the radiology department should be equipped with a wire grid, and the film-taking effect will be better. raised.
Scope of application: filming frame, filming bed, gastrointestinal bed, etc.
When a general customer inquires about a wire grid, it is first necessary to determine the grid ratio, size, grid type, grid density and focal length. Common grids: 10 grids of size 15×18 Scale: 1,103L/IN grid density. Usually the x-ray focusing grid frame 1m uses a 0.8m bed, and the film is the focal length of the gastrointestinal bed. about 5 meters. Therefore, when customers need to purchase wire grids, these parameters should be clearly realized.
But many people don’t know that different models need to be customized with different sizes of wire grids, but what is a wire grid?
(1) Variable size
From standard 5″ x 7″ to 14″ x 51″, 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 most common size is 15″ x 18″.
(2) Variable grid ratio
From 3:1 to 15:1, the grid ratio refers to the ratio of the height of the lead grid bars to the width of the gap. The more commonly used grid ratios are 8:1, 10:1, 12:1.
(3) Focal length range
From standard short focal lengths (26″-32″) medium focal lengths (34″-44″) long focal lengths (40″-72″, 48″-72″ 60″-72″) to infinity (parallel lines). The focal lengths commonly used in medicine are mainly 100cm, 130cm and 180cm.
(4) High grid density
From 60 or 70 lines/inch, to high density (85 lines/inch), ultra-high density (103 lines/inch), invisible lines (105 lines/inch), ultra-invisible lines (170 or 200 lines/inch) . The grid densities commonly used in medical are 85 lines/inch and 103 lines/inch.
The most important thing is to look at the size of the grid, what size to match, and what kind of optical machine it is used in. These are the questions that customers need to understand first. After understanding everything, they can determine what kind of grid to buy.
