The document discusses the components and functioning of an X-ray machine. It describes how X-rays are produced via the interaction of electrons with a target in an X-ray tube. The key components of the X-ray tube are the cathode, which emits electrons, and the anode, where the electrons collide. Rotating and stationary anodes are discussed. The document also covers technical components like the generator and control panel, as well as factors that affect X-ray production and quality.
