The imaging principle of X ray

X ray applied to medical diagnosis is mainly based on the penetration, differential absorption, photosensitization and fluorescence of X rays.
As X rays pass through the body, they are absorbed in varying degrees, such as the amount of X rays absorbed by the bone more than the amount absorbed by the muscles, then the amount of X rays passing through the body is different, thus carrying the information of the density distribution of the human body and the fluorescence (or photoreceptor effect) on the screen (or photographic film).
There is a great difference between strength and weakness.
Therefore, when developing or fixing on a fluorescent screen (or photographic film), it will show different density shadows.
According to the contrast of shadow and contrast, combined with clinical manifestations, laboratory results and pathological diagnosis, it is possible to determine whether a part of the human body is normal.
