Which type of scattering is primarily responsible for producing low-energy X-rays in a clinical setting?

In the context of clinical radiography, low-energy X-rays are primarily produced through coherent scattering. Coherent scattering, also known as classical or Rayleigh scattering, occurs when X-rays interact with matter without a significant loss of energy. During this interaction, the incoming X-ray photons are scattered in different directions, maintaining their initial energy level but altering their direction. This results in the production of low-energy photons that may not have enough energy to penetrate dense tissues effectively.

Understanding different types of scattering helps in recognizing how various interactions contribute to image quality and radiation dose. Coherent scattering, particularly at lower energies, mandates attention due to its limited diagnostic utility in imaging but can impact patient exposure and image gray levels in mammography.

The other options refer to different interactions involving X-ray photons and matter. Compton scattering involves the interaction of photons with electrons, leading to a transfer of energy and the production of scattered radiation, which can contribute to image contrast and diagnostic information but does not primarily produce low-energy X-rays. The photoelectric effect results in the complete absorption of the incoming photon, causing a significant interaction that contributes greatly to image formation but does not produce additional X-rays. Bremsstrahlung scattering is associated with high-energy electrons decelerating in the
