All diffraction methods are based on generation of X-rays in an X-ray tube. These X-rays are directed at the sample, and the diffracted rays are collected. A key component of all diffraction is the angle between the incident and diffracted rays. Powder and single crystal diffraction vary in instrumentation beyond this By then, CT examination times were dominated by interscan delays. After each 360° rotation, cables connecting rotating components (x-ray tube and, if third generation, detectors) to the rest of the gantry required that rotation stop and reverse direction. Cables were spooled onto a drum, released during rotation, and then respooled during. Medical x-rays come from a machine that is designed to emit radiation on command.
