What happens during the scatter interaction of X-rays with matter?

• A. X-rays are absorbed completely by the tissue
• B. X-rays pass through tissue and strike the receptor
• C. X-rays change direction without entering the tissue
• D. X-rays lose all their energy upon hitting the tissue

Answer: (C)

During the scatter interaction of X-rays with matter, X-rays change direction without entering deeply into the tissue. This process involves the incident X-ray photon colliding with matter (such as tissues in the body), resulting in the photon being deflected from its original path. The energy of the scattered photon may be slightly less than that of the incident photon, as some energy can be transferred to the electrons of the atoms in the tissue, but the primary characteristic of scattering is the change in direction rather than absorption or complete energy loss. This phenomenon is key in various imaging techniques as it contributes to the overall contrast and quality of the images produced. Understanding scattering helps dental professionals gauge how X-rays interact with human anatomy, which is crucial in ensuring safety and accuracy in diagnostics and treatments.
