The Poisson distribution is often a discrete likelihood distribution and its mass distribution perform is defined by
If the ray passes by inhomogeneous objects, variable μ(x) could be the linear attenuation coefficient at Just about every level on the ray path
Inherent filtration is existing due to the design in the x-ray tube. It is a part on the tube and can't be eliminated. The x-ray tube incorporates a leaded glass masking or envelope all-around it. The glass includes a thinner spot in it called the window. This window is positioned under the anode.
