How X-ray Machines Function
You can lead a life without fearing x-rays because the thought of shooting radiation is scary even though x-rays are safe. In this article you will understand x-rays and how the machines work. Xrays were discovered in 1895 when a physicist was trying out electron beams in a gas release tube. He performed this by lighting the beam so that that the fluorescent in the lab glowed. Normally there is a glow in fluorescents in case they are put before electromagnetic radiation. It was here that x-ray was discovered when the surrounding cardboard on the tube blocked the radiation.
He went on to place many objects in front of the fluorescent screen and the tube to see what would block the radiation. This time he put his hand in front, and he saw his bones projected in the screen. It was here that that the discovery of x-ray happened and he also discovered its impact on the medical field so we can define x-ray as electronic radiation. Xray can compare to visible light although the human eye cannot see the short wavelength. This shortness of wavelengths show the high energy in x-rays.
these short wavelengths can go through many objects including the human body tissues. This is why through an x-ray we see bones through a human body. If you place a detector on the other side, the x-rays that go through the body they appear black, however, anything that is absorbed by the x-rays appears white such as bones.
At the center of an x-ray machine is a pair of an electrode in the vacuum glass tube. If a cathode is charged negatively it becomes a filament that is heated through the current from the x-ray machines. The filament’s electrons come off to the surface.
Moreover, electrons are pulled through the tube after a tungsten anode which is positively charged. This process form enough energy to form an x-ray using a form of high energy photon. There is thick lead in photon but using a small window, but they escape using a narrow beam to the point to x-ray. Films are developed after the capturing of the x-ray patterns. However a chemical reaction happens instead of a visible light.
You can further see soft tissues through an x-ray. This is done by putting contrast media in the body. There is a liquid known as contract media which is injected so that there can be ease in x-ray absorption. Barium is swallowed to that the systems can absorb x-rays the media is injected in the body so that they systems are visible. Lung cancers can be diagnosed using this procedure along with other types of cancer.
