What is an X -ray image?
The X -ray image is a picture taken with X -ray technology that allows you to see the inside of the object. X -rays, also called X or Roentgen radiation, are a type of electromagnetic radiation with a very short wavelength. The radiation with the shortest wavelengths, hard X -rays are strong enough to penetrate objects, making them a useful tool for security screening, medical diagnostics and looking at the interior of crystals. The X -ray image is a two -dimensional image of objects in white shades on a black background. In the X -ray image of the body, bones that are dense, they absorb more radiation than soft tissues that are less dense. This radiation absorption is called attenuation. Where more radiation is weakened, less radiation is able to pass to the other side of the object. Where a smaller attenuation, more X -rays is able to fully pass through the subject.
radiation that passes on dThe rule of the subject is captured by an X -ray sensitive plate. Where it hits on the board, radiation excites electrons or subatomical negatively charged particles. In the photographic board, an old means of viewing an X -ray image, these exposed areas would darken, the less exposed area would prove gray and non -exposed areas would remain white. That is why the X -ray image of the body shows bones like white, soft tissues like gray and black background.
Today, the photographic board was largely replaced by a calculated radiography that uses photostimulatory phosphor boards (PPS boards). In this radiation process, it penetrates the subject, hits the plate and excites electrons in areas where the subject is less dense. This piece of procedure is similar to the use of a photographic board, with the exception of less radiation. Less radiation is preferred, as high amounts of radiation can harm cells harmfully. After revealing the PSP board, electrons are laser radiation and the signal then passes through the computer and translateIt is in the digital image.
In the medical environment, an X -ray image is usually used to explore bones, but a softer X -ray or one with longer wavelength can be used to look at soft tissues. Radiography also includes fluoroscopy, imaging technique that achieves a moving image of the body with lower resolution. This is used to explore moving tissues such as blood flow or to conduct surgery. X -ray technology also has many industrial uses, such as luggage scanning at the airport, viewing the interior of the cargo box and checking the interior of the products to ensure safety and quality.
