Useful Tips to Understand about How X-ray Machines
Although x-rays are safe, shooting radiation sound scare but if you want to be at peace, you can x-ray and lead an x-ray fear free life. This article seeks to discuss x-rays and how their machines works. In 1895 x-rays were discovered during such time when a physicist was experimenting an electron beam in the tube for gas release. He did this by the light the beam, and the fluorescent in the lab lit. Normally there is a glow in fluorescents in case they are put before electromagnetic radiation. The discovery of x-ray happened when the cardboard surrounding the tube did not prevent the radiation.
He continued placing several objects before the fluorescent screen and tube to find out if any of them would prevent the radiation. The bones of his hand were projected when he put his hand before the fluorescent and the tube. He discovered x-rays and its application in the medical field, so an x-ray is electronic radiation. Xray can compare to visible light although the human eye cannot see the short wavelength. 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. 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.
In the center of the x-ray machine in the vacuum glass tube there is an electrode pair. When a cathode is charged negatively is a heated filament using the current of 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. Photons have thick lead however a small window allows escape through a narrow beam to the patient. This pattern of x-ray is captured by the camera and films are developed. However a chemical reaction happens instead of a visible light.
It becomes possible to see soft tissues through the x-ray. Contrast media is put in the body. Contract media is infused in the system making it easy for the absorption of x-ray. The body becomes visible after media is injected so that x-rays can absorb it after barium is swallowed. Most cancers including lung cancer are normally detected using this process.
