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. The discovery amazed many people. But many people feared that this machine could obliterate privacy since they believed that it could look beyond walls and doors.
The Usage of X-ray in the Medical Field
X-ray became very important in its use the medical field. This was acknowledge immediately after the publication of Roentgen's finding in the year 1895. In America it was immediately used to diagnose bone fracture jyst weeks after its debut.
X-rays, What are They?
Waves of electromagnetic energy are x-rays. They are similar to lights rays however they are shorter. Low density targets are usually the things that x-ray can pass through without being interrupted. It is reflected or absorbed if the targets are of high density like the human body. The reason for this is because x-ray cannot pass through tightly packed atoms. It completely passes through flesh that is why it is dark in the x-ray image. The areas where the rays could not pass through are the shown as the light areas.

Thomas Edison invented the x-ray fluoroscope in the year 1896. It was used by the American physiologist named Walter Cannon to observe the movement of barium sulfate in the digestive track of animals and even humans. The first x-ray tube to be used for medical purposes was designed in the year 1913 by the American chemist named William Coolidge. Since then x-ray became the most accurate tool for internal diagnosis.
Modernised X-ray Machines
Today there is a two classification of the new xray machines for security, the "hard" and "soft" X-ray. "Soft" X-rays are used to take photographs of internal organs and bones. If it is done repeatedly it cause some tissue damage but overall since it operates at a low frequency it is quite harmless. However "hard" X-rays are in high frequency. They can destroy the tissue since they are designed to destroy specific molecules within specific cells. They are usually used in the cancer treatment, specifically radiotherapy. Cyclotrons or synchrotrons are required for the production of "hard" X-rays because it needs a high voltage to be produced.
Security scanner in airports is one of the most popular uses of X-ray machines from www.xrayimagingusa.com today, they are used in order to search airport baggage. They are machines that uses very low power. The scan is done in a manner that it doesn't cause damages just like how doctors scan bones.
