The selection of the appropriate x ray grid needs to be determined according to the size of frequently applied kilovolt

In clinical applications, many people generally think that the higher the x ray grid ratio of the filter grid, the stronger the ability to eliminate scattered rays, and the greater the patient’s exposure. The greater the grid density, the greater the dose to the patient. In fact, this is not the case. When using the wire grid, it is not that the higher the grid ratio, the greater the grid density.
In daily work, the selection of the appropriate grid needs to be determined according to the size of frequently used kilovolts. For example, when using high kilovolts for photography, it is best to apply a 10: 1 or 12: 1 grid. For 14CM thick parts, generally use 8: 1 or 10: 1 filter grid.
