As X-rays pass through materials, their intensities decrease by absorption, and their directions slightly change due to refraction. X-rays change their directions the most when they run parallel to the density interface and more X-rays land on one side of the interface while leaving a "gap" of X-ray intensity on the other side. This change in direction generates a pair of dark and light gray levels on a projection image highlighting interfaces of two materials with different densities.
