In the previous article, we have introduced the function of the x ray grid and the common types of grids. So, do you have any doubts about the parameters of the grid? What are the functions of the grid parameters? Next, let’s take a look at the important parameters of the grid.
The main specifications of the grid are three kinds of grid density, grid ratio and focal length. Let us look at the tam grid density separately: the number of lead bars arranged per unit distance. The greater the grid density, the stronger the ability to absorb scattered lines. Gate ratio: The ratio of the height of the lead strip to the distance between the lead strips. The greater the gate ratio, the stronger the ability to filter out the rays, and the stronger the ability to absorb the scattered rays, the more the amount of absorbed original rays is. Focal length: The vertical distance from the focus (the point where the lead extension line converges) to the center of the grid.
