As an X-ray beam passes through material, there exist three alternatives for each photon:
  1. 1.

    It can penetrate the material without interacting

  2. 2.

    It can interact with material and be completely absorbed by depositing its energy

  3. 3.

    It can interact and be scattered from its original direction, possibly depositing a part of its energy
