Electromagnetic energy carried by photons

Produced by movement of electrons in atoms

Shorter wavelength of higher energy

How X-Rays Work (cont..)

Soft tissue doesn't show up clearly

Contrast media liquids absorb X-rays more effectively

X-ray light sets off the chemical reaction

Why Do We Use X-Rays
