How to do the proper use of X-ray grid?

X ray grids should be standardized when used, otherwise they will not be able to filter out scattered rays and fail to 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. The center line of the X-ray can be tilted at a certain angle according to the tilt direction of the lead bar without deviating from the center line of the grid 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 grid to ensure the quality of the image.
When placing the x ray grid, pay attention to the focus surface facing the X-ray generation direction, and place it in the incident direction of the human body and the X-ray. In order to make the original emission line pass through the x ray grid to the greatest extent, the X-ray centerline during exposure It can be tilted to the direction of the lead bar and cannot deviate from the center line of the x ray grid, so that the X-ray radiation direction and the direction of the lead bar can be on the same horizontal line to pass the original emission line to the greatest extent, and because the directions of the scattered rays are different and messy Therefore, the scattered rays can be well absorbed and the image quality can be improved.
