What is the role of the grid in filming?

The grid should be placed between the object to be measured and the receiving image, which filters out most of the scattered lines and can pass through a small portion of the scattered lines.

At the same time, the grid can improve the quality of the X-ray machine, and it can also reduce the gray level and improve the bright contrast. The use of the grid can improve the quality of the film when the thickness and density of the object being photographed are relatively large. It is recommended to use a high frequency machine to make film shots, and the effect will be better.

If the DR X-ray machine needs to be equipped with a grid, you need to know the brand and model of your DR. Because different DR match different grid.

If your X-ray machine is performing well and you have a price, you can choose not to use the grid.
