X-Ray machine

The application of X-ray in medical diagnosis is mainly based on X-ray penetration, differential absorption, photosensitization and fluorescence.Because x-rays through the body, by the absorption of different degree, such as bone absorption of X-ray quantity more than the amount of muscle absorption, then through the body after the X-ray quantity is different, so carry the body ministries density distribution of information, on the screen or film caused by fluorescence function or the strength of the photosensitive action there is a bigger difference, thus or photographic film on the screen (after developing and fixing) will show different density shadow.According to the contrast of shade intensity, combined with clinical manifestations, laboratory results and pathological diagnosis, can determine whether a part of the human body is normal.As a result, X-ray diagnosis has become the world's first non-invasive visceral examination technology.
