- If a grid is made to match the size of a 14 x 17 inch image receptor, the surface of the grid that measures 14 x 17 is called the face of the grid. A line, called the center line, is usually drawn on the face of the grid, which lets the radiographer know the direction of the grid lines, since they are hidden by the grid’s cover.

The antiscatter grid plays an important role for enhancing image quality in projection radiography by transmitting a majority of primary radiation and selectively rejecting scattered radiation.
Grid cutoff refers to a phenomenon in radiography where the lead strips of an anti-scatter grid absorb some of the primary X-ray beam, resulting in reduced image contrast and visibility of anatomical details.
Feb 6, 2015 · According to Safety Code 35, a grid alignment test should be performed annually to check the performance of the grid. The purpose of this experiment was to test the alignment of the radiographic grid in the bucky mechanism with respect to the central ray of the x-ray tube.
On the basis of not deviating from the center line of the X-ray grid, the X-ray center line can be inclined at a certain angle according to the inclination direction of the lead rod, so that the X-ray radiation direction is consistent with the lead.
In the X-ray photography, the center line of the X-ray is aligned with the center of the grid, and the original ray projection direction is in the same direction as the gap between the lead bars of the grid.
Sep 21, 2022 · X-ray grids are devices used in radiography to improve the quality of images by reducing the amount of scattered radiation that reaches the X-ray detector or film. The basic purpose of X-ray grid use is to enhance the contrast and quality of the medial image by removing the scatter radiation.
