Absorption of X-Rays • In diagnostic radiology, both Compton and photoelectric absorption processes occur. • Compton dominates at higher energies, while photoelectric absorption is important at lower energies. • Photoelectric process: X-ray photon interacts with a bound electron in the atom's shell,...
Absorption of X-Rays • In diagnostic radiology, both Compton and photoelectric absorption processes occur. • Compton dominates at higher energies, while photoelectric absorption is important at lower energies. • Photoelectric process: X-ray photon interacts with a bound electron in the atom's shell, transferring all its energy to the electron, which may be released inner it from its orbit -O 5
