Absorption
Answer: The characteristics of an anatomical part are influenced by its
composition, such as thickness, atomic number, and tissue density.
Tissue Density
Answer: Tissue density refers to the compactness of cellular structures within a
tissue.
Differential Absorption
Answer: Differential absorption is the difference between the x-ray photons that
are absorbed through photoelectric interactions and those that pass through the
body without being absorbed.
Do varying atomic parts absorb the primary beam to the same degree?
Answer: No, different tissues like bone, air, and soft tissue absorb the x-ray beam
at varying levels.
Attenuation
Answer: Attenuation is the reduction in the energy or number of x-ray photons
interacting with the primary beam.
What are the 2 processes that occur during beam attenuation?
Answer: The two processes involved in beam attenuation are absorption and
scattering.
