WebThe intensity of X-Rays transmitted through a substance relative to the initial beam intensity is given by the equation below. I = I 0 ⋅ e − μ x. I0 is the initial intensity of the photons, x is the tissue thickness (distance travelled), and μ is the linear attenuation coefficient for the photon energy. Web9 de ago. de 2024 · The x-ray beam originates from a point source within the x-ray tube. It is due to this point source nature that x-ray beams will all possess 'beam divergence'. As the beam exits the x-ray tube the beam will 'diverge' while the center point (central ray) of the beam will not suffer from any divergence.
