Each element in the matrix can in principle have a different value of the associated linear attenuation coefficient. The equation for the attenuation can be expressed The quantity imaged by x-ray systems is the linear attenuation coefficient, which in turn depends on the cross-sections of x-ray interactions with matter. Here I will discuss the physics of these quantities and will also emphasize the implications for extracting the energy-dependent information. 2011-09-01 The linear attenuation coefficient μ is a material property quantifying ability to attenuate radiation. A material of thickness 1 cm and linear attenuation coefficient μ 11 reduces the initial flux from I o to I o /e μ*1 cm. The unit of the linear attenuation coefficient is 1/cm.
