X-Rays (X-Radiation) is the radiation of Electromagnetic Waves, just as a visible in light. X-Rays tests are generally done to show the structure of bones and some tissues of other parts also. A machines sends X-ray particles individually, these particles called photons. A computer or special film is used to record the images that are created. Dense part of the body (such as bones) will block the maximum the part of X-Ray Particles. That portion will become white in the film. . Metal and contrast media (special dye used to highlight areas of the body) will also appear white. The portion where only air is present will become white, and the portion of muscle, fat, and fluid will appear as shades of gray.

Digital radiography is a type of X-Rays imaging, where digital X-ray sensors are utilized rather than customary photographic film. Favourable circumstances incorporate time productivity through bypassing synthetic preparing and the capacity to digitally exchange and improve pictures. Additionally less radiation can be utilized to deliver a picture of comparative complexity to routine radiography.
