Smart Tips For Finding
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. In this article, we will discuss how the x-ray machines work and understand x-rays. In 1895 x-rays were discovered during such time when a physicist was experimenting an electron beam in the tube for gas release. He performed this by lighting the beam so that that the fluorescent in the lab glowed. 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.
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. This time he put his hand in front, and he saw his bones projected in the screen. 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.
these short wavelengths can go through many objects including the human body tissues. 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.
In the center of the x-ray machine in the vacuum glass tube there is an electrode pair. If there is negative charging of a cathode there is a heated filament that is through the x-ray machines current. 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. 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. 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. Most cancers including lung cancer are normally detected using this process.
