Medical x ray ----Great Discovery in World Medical

One of medicine's most remarkable achievements is the use of X-rays to see inside the body without having a surgeon wield a scalpel. The suitable medical machine are mobile x ray machine , c arm x ray machine , digital x ray machine and so on .
X-rays are used for much more than identifying injuries from accidents. They are used to screen for, diagnose, and treat various medical conditions. X-rays can be used on just about any part of the body—from the head down to the toes—to identify health problems ranging from a broken bone to pneumonia, heart disease, intestinal blockages, and kidney stones. And X-rays cannot only find cancerous tumors, but can often destroy them.
Along with their tremendous value, medical X-rays have a drawback: they expose people to radiation. FDA regulates radiation-emitting products including X-ray machines. But everyone has a critical role in reducing radiation while still getting the maximum benefit from X-ray exams.
X-rays are a form of electromagnetic radiation that can penetrate clothing, body tissue, and internal organs. An X-ray machine sends this radiation through the body. Some of the radiation emerges on the other side of the body, where it exposes film or is absorbed by a digital detector to create an image. And some of it is absorbed in body tissues. It is the radiation absorbed by the body that contributes to the "radiation dose" a patient gets.
    Nowadays, there are more and more medical manufacturer that they spare no effort to improve x ray machine , and reduce x ray dose on patients as much as they can. So don’t worried about the radiation from x ray, it won’t do much harm to our body.
