Use the X-ray grid to increase the X-ray dose to offset the consumption of the X-ray grid

Since the X-ray grid has the characteristics of filtering out scattered rays, it will also absorb a small part of the original emission line while filtering out the scattered rays. Therefore, the exposure conditions should be increased to a certain extent to increase the original emission line. The amount of emission lines to offset the original emission lines consumed by the X-ray grid to ensure image quality. It is necessary to increase the amount of the original emission line by means of tube voltage compensation, and it can be concluded that the tube voltage value of the X-ray grid with low grid ratio is low, and the value of the tube voltage used by X-ray grid with high grid ratio High, because the larger the grid ratio, the stronger the ability to filter out scattered rays. Similarly, the higher the amount of original emission rays absorbed.
