The grid can be installed on the film rack or film bed for use

The main function of the grid is to filter stray x-rays. Stray scattered rays will cause normal rays to change the propagation direction and form rays with different propagation directions, called scattered rays.
There are many types of grids. According to its structure, materials and methods, it can be divided into the following categories. According to its structure, it can be divided into three types: convergence grid, parallel grid and cross grid. According to its material classification, it can be divided into metal grid and non-metal grid. According to the method, it can be divided into fixed grid and mobile grid.
A wire grid is a device that improves image quality by filtering out scattered rays. If you don’t filter out these stray scattered rays, it will not only affect the quality of the image, but also make the patient receive unnecessary radiation and endanger the health of the body.
Before use, adjust the wire grid to confirm the installation position and direction of the device, otherwise it will not play a role in filtering out the scattered rays, and it will also affect the image quality. The front of the grid is the focal plane. The focus plane should face the tube when installed.
