What is the imaging principle of X-ray?

X-ray imaging principle is:

1 and x-rays have penetrability, fluorescence effect and photographic effect;

2. Because the density and thickness of human tissues are different, when X-rays pass through various human tissues, they are absorbed to different degrees, so the amount of X-rays reaching the screen or film is different, and images with different black and white contrast are formed on the screen or X-rays.
