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. This article seeks to discuss x-rays and how their machines works. Electron beams were being released in a gas tube and during that time x-rays were now discovered by a physicist in 1895. The fluorescent in the lab glowed when the light in the beam was lit. Fluorescents glow if they are put in front of electromagnetic radiation. When radiation was blocked by the cardboard that was surrounding the tube, the x-ray was discovered.
In his bid to know if there is any object that would block the radiation he continued placing many of them before the tube and the fluorescent. He even put his hand before the tube and fluorescent, and here he saw his hand bones projected on the screen. Xray was discovered at this point, and he also discovered that it has benefits to the medical front so we can comfortably 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.
Meaning they can pass through several objects and human tissue. No wonder in an x-ray we see the bones through a human body. When a detector is placed on the other side, x-rays passing through the body assume a black shadow but anything like bones absorbed by the x-rays is white.
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 surface is filled with electrons from the filament.
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. 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. But this time instead of a visible light there is a chemical reaction.
From the x-ray you can see soft tissues. Contrast media is put in the body. Contract media is infused in the system making it easy for the absorption of x-ray. Barium is swallowed to that the systems can absorb x-rays the media is injected in the body so that they systems are visible. Most cancers including lung cancer are normally detected using this process.
