You need to know this before you buy an X-ray Grid

There are many customers asking questions about the X-ray Grid. Let’s take a look at some common questions about the X-ray Grid.
How The X-ray Grid works:
An X-ray Grid is the perfect way to eliminate scattered rays and get a clearer picture.
When should You use an X-ray Grid:
An X-ray Grid should be used when the body is larger than 10cm in thickness.
How the X-ray Grid is produced:
Ordinary filter grid: aluminum and lead strips are cut into pieces, then stacked together, and then sealed with aluminum or carbon base.
Breast filter grid: Cut the graphite plate, then fill it with lead, and finally package it as a whole
Common Specifications and definitions of X-ray Grid:
Grid density: How many pairs of lines are in each centimeter (cm)/inch
Raster ratio: the ratio of the thickness of the X-ray grid to the gap width of the lead strip
Dimensions: Common dimensions 15 ‘*18’ inches, 18 ‘*18’ inches and other custom dimensions
Focal length: The distance between the ball tube and the base plate of the filter
What is the relationship between the scattered lines and the dose?
The tube voltage directly determines the mass of the ray, which is the softness and hardness of the ray.
The energy spectrum distribution of a ray directly determines the number of scattering lines. Generally speaking, the higher the dose, the more scattering lines
Why the higher the tube voltage is, the more scattering lines are:
The scatterers excited by high-energy rays are more concentrated and powerful, while the scatterers excited by low-energy rays are scattered and weak
How to correctly select An X-ray Grid:
Senior executives should choose X-ray grid with high grid ratio, grid with 10:1 above 90kV and grid with 8:1 below 90kV
How an X-ray Grid should be placed:
With vertical lines or labeled faces up, use the crosshairs that the collimator marks to point at the middle line of the X-ray Grid
