What is the voltage compensation of x-ray grid

The internal structure of the x-ray grid is formed by intersecting many thin lead bars.
As the main component of the x-ray grid is lead chaff, which not only blocks the scattering line, but also inevitably blocks a part of the primary rays, to a certain extent, reduces the sensitivity of the film. Therefore, in photography, it is necessary to increase the exposure conditions, that is, to improve the X-ray penetration ability by increasing the tube voltage, rather than without the x-ray grid. In order to achieve the purpose of compensation. Specific compensation data should be combined with clinical use to obtain the general situation, the low-grid filter applies to low-voltage tube voltage; the high-grid applies to high-voltage tube voltage.
