Coherent Scatter - Video Lesson

Hey, everybody. Welcome back. This lesson is about coherent scattering. One of the few ways that a photon can interact in the human body. So here's what happens. The x-ray photon enters an atom in the body, The x-ray photon energy is temporarily absorbed by the entire atom. The x-ray photon energy is then immediately eject and out of the atom as a scatter photon with all of its original energy, but in a different direction. That's why it's called coherent scattering. So with this interaction, it's a photon in and a photon out. Coherent scattering is sometimes given other names. Like Thompson scattering, classical scattering, unmodified scattering, elastic scattering, and rayleigh scattering. Each of these names are used for different reasons. So just be aware that coherent scattering sometimes does
