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 you will understand x-rays and how the machines work. Electron beams were being released in a gas tube and during that time x-rays were now discovered by a physicist in 1895. He performed this by lighting the beam so that that the fluorescent in the lab glowed. If electromagnetic radiation comes close to fluorescents they glow. It was here that x-ray was discovered when the surrounding cardboard on the tube blocked the radiation.
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. 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.
Meaning they can pass through several objects and human tissue. This is why through an x-ray we see 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. 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.
On the other hand, the tungsten anode that is positively charged pull the electrons across the tube. In this process ample energy is formed to create x-rays in form of form of high energy photon. There is thick lead in photon but using a small window, but they escape using a narrow beam to the point to x-ray. This x-ray light pattern is received by a camera and films are developed. A chemical reaction occurs and not a visible light.
You can further see soft tissues through an x-ray. This is done by putting contrast media in the body. Contract media is infused in the system making it easy for the absorption of x-ray. 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.
