DESCRIPTION: The use of X-Ray imaging has revolutionised the field of medicine. Typical X-Ray imaging relies on the emission of radiation from a tungsten anode. In a typical X-ray machine, a cathode is heated up and releases electrons. These electrons are then subjected to a high voltage difference between the cathode and the anode. This causes electrons to hit electrons within the atoms of the anode which in turn knocks them out of their orbit around the anode atom’s nucleus. Electrons from a higher orbital in the anode atom then move to fill in the space of the ejected electrons, releasing energy in the form of X-ray radiation in the process. The beams of radiation are then shot at a patient and absorbed by structures in the patient’s body when the energy of the X-ray matches the energy required to move an electron up one orbital in the atom being hit. Structures made of larger atoms such as Calcium in bone, will absorb more X-rays, as these larger atoms have larger orbitals that...
