Useful Tips to Understand about How X-ray Machines
X-rays are safe even if radiation shooting can sound scary however if you want peace of mind by understanding x-rays and be free of fears. This article seeks to discuss x-rays and how their machines works. Xrays were discovered in 1895 when a physicist was trying out electron beams in a gas release tube. The fluorescent in the lab glowed when the light in the beam was lit. 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 continued placing several objects before the fluorescent screen and tube to find out if any of them would prevent the radiation. He even put his hand before the tube and fluorescent, and here he saw his hand bones projected on 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. Even though the wavelength is short x-ray can compare to visible light only that the human eye cannot see it. There is high energy to x-ray because of the short wavelengths.
It means that this wavelength can pass through the human body and other objects. No wonder in an x-ray we see the 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.
In the vacuum glass tube, there is an electrode pair at the middle of the x-ray machine. If a cathode is charged negatively it becomes a filament that is heated through the current from the x-ray machines. The electrons come off from the surface of the filament.
Further, tungsten anode is charged positively attract the electrons through the tube. This process form enough energy to form an x-ray using a form of high energy photon. Even if there is thick lead photon still escape through a small window and a narrow beam to the patient. Films are developed after the capturing of the x-ray patterns. A chemical reaction occurs and not 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. Upon swallowing barium, x-rays absorb the media which is infused in the body to make the body visible. Lung cancer is easily diagnosed through this process as well as other cancer types.
