... to faint light. This is then converted to electric signal and been reformed as an image by a computer (The images come sin grey scale). Production of x-ray The x-ray machine consists of an x-ray tube that contains two essential electrodes: the anode (target) made out of tungsten or any heavy metal and the cathode, which is used for the emission of electrons. The typical potential difference (kilo electrons kV) needed is the force that makes the electrons to accelerate. When the electrons are emitted from a heated filament, it accelerates at a high voltage. This allows the electrons to collide with the metal target. The kinetic energy is transferred into electromagnetic energy. Suddenly the collision slows down and then x-rays are produced in all direction of the target. The projectile electron (electron travelling from the cathode to the anode) interact with the outer shell of the target atom, however sufficient energy ...
