How to use the x ray grid correctly

How should we use and place it to correctly use the x ray grid to filter out scattered rays and improve image quality? Let’s take a look at it.

The wire x ray grid should be standardized when used, otherwise it will not function to filter out the scattered rays, and will not achieve the purpose of use. The x ray grid is divided into two sides, the front is the focusing surface, and the focusing surface and the focusing surface are literally understood as the side facing the focus of the X-ray tube, that is, the side with the convergence line. When placing the x ray grid, be sure to pay attention to the focus surface facing the X-ray incident direction. The opposite side of the focal plane is called the back focal plane. Pay attention to the X-ray irradiation direction during exposure. On the basis of not deviating from the center line of the x ray grid, the X-ray center line can be tilted at a certain angle according to the tilt direction of the lead bar to make the X-ray radiation direction consistent with the lead bar direction. This can ensure that the maximum amount of the original emission line passes through the wire x ray grid to ensure the quality of the image.
