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, we will discuss how the x-ray machines work and understand x-rays. 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. 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. 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. It is similar with visible light, but the wavelength is short that human eyes cannot see it. The short wavelengths confirm that x-ray has high energy.
It means that this wavelength can pass through the human body and other objects. This is the reason that though a human body we can see bones in an x-ray. 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.
In the vacuum glass tube, there is an electrode pair at the middle of the x-ray machine. 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. In this process ample energy is formed to create x-rays in form of 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. This pattern of x-ray is captured by the camera and films are developed. But this time instead of a visible light there is a chemical reaction.
You can further see soft tissues through an 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. 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.
