The Functions of X-ray Machines

X-rays are safe even if radiation shooting can sound scary however if you want peace of mind by understanding x-rays and be free of fears. In this article, we will discuss how the x-ray machines work and understand x-rays. Xrays were discovered in 1895 when a physicist was trying out electron beams in a gas release tube. He did this by the light the beam, and the fluorescent in the lab lit. Fluorescents glow if they are put in front of 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. 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. 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.

It means that this wavelength can pass through the human body and other objects. 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.

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 is the process that forms ample energy to create an x-ray in a high energy photon form. 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. A chemical reaction occurs and not a visible light.

It becomes possible to see soft tissues through the x-ray. This is done by putting contrast media in the body. Contract media is a liquid that better absorb x-rays than plain soft tissue. Upon swallowing barium, x-rays absorb the media which is infused in the body to make the body visible. Lung cancers can be diagnosed using this procedure along with other types of cancer.
