Compton Scatter - Video Lesson

Hey, everybody. Welcome back. This video discusses another type of radiation interaction called Compton Scatter. This is the most common, but the least desirable thoughts on interaction. It's important to understand compton scattering because it negatively affects all three areas of concern. Patient dose, occupational dose, and the image quality. So here's what happens. The x-ray photon enters an atom in the body, and the x-ray photon energy is partially absorbed by a loosely bound outer shell electron. This results in the electron being knocked out of its orbit, which we call ionization. The electron is commonly called a compton electron, because it was created by compton scattering. The rest of the photon energy immediately exits the atom as a scattered photon. It has less energy
