X-Ray was invented by a Germans physicist Wilhelm Conrad Roentgen. By the way, when do people use X-ray? Correct. When they are ill.

If doctors don't use the X-Ray, they will miss some important information which are very useful in making a diagnose on the patient's disease. And this

will sometimes cause the doctor to be inaccurate in prescribing the medicine to cure the illness. Not all patients agree with the use of X-Ray examination, however 10% of patients disagree with the use of X-Ray examination. They think that using X-Ray examination will spend a lot of money. Well, I'm not surprised. Another reason is the radiation of X-Ray has some risks to the body tissues. The rest of the patients or 30% of patients remain silent because they have no idea whether the use of X-Ray examination is really beneficial or not?

Well, as a result of this controversy, many people are planning a traditional health cure to avoid the high cost of hospital care. While hospitals insist on having X-Ray examinations on patients to get an accurate diagnose, although the cost is very high.
