What is the voltage compensation of x-ray grid
The internal structure of the x-ray grid is formed by intersecting and arranging a large number of thin lead bars in an orderly manner.
Lead chaff serves as the core and main component of the x-ray grid. It can effectively block and filter out scattered rays generated during X-ray imaging. However, it will inevitably block a certain part of primary rays at the same time, which will reduce the imaging sensitivity of the X-ray film to a certain extent.
Therefore, in actual X-ray photography and clinical radiography work, it is essential to appropriately increase the exposure conditions. The reasonable operation is to enhance the penetration capability of X-rays by properly raising the tube voltage, instead of removing the x-ray grid directly, so as to realize the effect of exposure compensation.
The specific compensation parameters and data need to be summarized and formulated combined with actual clinical application experience. In general, a low ratio x-ray grid is suitable for matching low tube voltage, while a high ratio x-ray grid is applicable to high tube voltage imaging scenarios.
