Machines for X-ray Procedures
On their discovery in the year 1895, it was proclaimed as the new scientific wonder and greatly enjoyed by many people. Bones and bones with silhouetted jewelry were taken pictures and it became very popular among circus patrons. People were clearly amazed with this discovery. But many people feared that this machine could obliterate privacy since they believed that it could look beyond walls and doors.
The Medical Could Use X-ray
In the field of medicine x-ray became very important. This was acknowledge immediately after the publication of Roentgen's finding in the year 1895. The X-ray machine was immediately utilized in America to diagnose fractured bones just mere weeks after its introduction to the market.
X-rays, What are They?
Xray security are electromagnetic energy. They are similar to lights rays however they are shorter. There is no interruption when they pass through targets especially in low density. In the cases human bodies or targets are of high density, the x-ray usually is reflected or absorbed. Tightly packed atoms do not allow short waves to come through. So an X-ray image presents dark areas where the waves pass through for example flesh. The areas where the rays could not pass through are the shown as the light areas.
On the year 1896 Thomas Edison invented the x-ray fluoroscope. It was used to monitor the movement of barium sulfate in the digestive track of animals and human by the American physiologist Walter Cannon. William Coolidge who is an American chemist designed the first x-ray tube to be used in the field of medicine in the year 1913. The x-ray then became the most notable instrument for internal diagnosis. Read this for example: http://www.huffingtonpost.com/smartertravel/10-ways-to-speed-through-_b_2213174.html.
X-ray Machines that are New
Today there is a two classification of the X-ray machine from http://xrayimagingusa.com, the "hard" and "soft" X-ray. When taking pictures of internal organs and bones "soft" X-rays are used. They are relatively harmless because they operate at a low frequency, unless they are repeated all the time they can cause a little damage in the tissue. On the other hand "hard" X-rays operate at high frequency. Tissue damage is done because it is designed for destroying molecules of particular cells. It is used the treatment of cancer called radiotherapy. Cyclotrons or synchrotrons are used in order to generate the high voltage needed to produce "hard" X-rays.
Security scanner in airports is one of the most popular uses of X-ray machines today, they are used in order to search airport baggage. They are machines that uses very low power. Through this machine the baggage of the passengers are scanned just like what doctors do to the bones, in a very unobtrusive manner that it can't damage the properties inside the baggage.
