What are the characteristics of the grid?

Speaking of the x-ray grid, mainly used for chest racks, X-ray machines, etc., it can make the image more clear, and can be filtered to the scattered line, improve the contrast, the thickness and density of the object is relatively large The use of the grid below can improve the quality of the film. It is recommended to use a high frequency machine to make film shots, and the effect will be better. Let’s take a look at the characteristics and functions of the grid.
Grid Features:

1. The application of high-purity lead in the grid provides high efficiency in anti-scattering.

2. The accurate combination of lead and aluminum strips makes high quality images possible

3, the smooth aluminum cover wrapped with lead grid, and enamel, so that the grid is protected from heat and dust, long-term exemption from maintenance, P & J grid in the following aspects:

1) Variable size from standard 5 x 7″ to 14 x 51″, the size of the grid is one inch larger than the corresponding film size.

2). The variable gate ratio is from 3:1 to 15:1, and the gate ratio refers to the ratio of the height of the lead grid strip to the width of the gap.

3). The focal length ranges from standard short focus (26″-32″) (34″-44″) far focus (40″-72″, 48″-72″60″-72″) until infinity (parallel line)
