AbstraktAbstract
Traditionally, radiography is burdened by the fact that standard X-ray tube spectra are polychromatic and attenuation process in matter is energy dependent, where low-energy X-rays are preferentially absorbed. This beam hardening effect has several consequences: radiograms took noisy especially when low-energy photons are detected, empty holes look filled in computed tomography and observed object looks flatter than it should be. It will be shown it this paper that these problems can be solved using the "linearized signal to equivalent thickness" beam hardening correction method.
