How X-ray Machines Function
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. In this article you will understand x-rays and how the machines work. In 1895 x-rays were discovered during such time when a physicist was experimenting an electron beam in the tube for gas release. The fluorescent in the lab glowed when the light in the beam was lit. If electromagnetic radiation comes close to fluorescents they glow. When radiation was blocked by the cardboard that was surrounding the tube, the x-ray was discovered.
He continued placing several objects before the fluorescent screen and tube to find out if any of them would prevent 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. Even though the wavelength is short x-ray can compare to visible light only that the human eye cannot see it. This shortness of wavelengths show the high energy in x-rays.
Meaning they can pass through several objects and human tissue. No wonder in an x-ray we see the bones through a human body. After placing a detector on the other side, when x-rays pass through a body a black shadow is seen however there is a white appearance of anything that absorbs the x-rays such as bones.
At the center of an x-ray machine is a pair of an electrode in the vacuum glass tube. When a cathode is charged negatively is a heated filament using the current of 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. Photons have thick lead however a small window allows escape through 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.
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. Lung cancer is easily diagnosed through this process as well as other cancer types.
