What does it do?
A form of X-ray imaging, digital radiography uses x-ray sensors to produce an image rather than traditional photographic film that uses chemical processing to produce an image.
What are the advantages?
Instead of X-ray film, digital radiography uses a digital image capture device. This gives advantages of immediate image preview and availability; elimination of costly film processing steps; a wider dynamic range, which makes it more forgiving for over- and under-exposure; as well as the ability to apply special image processing techniques that enhance overall display quality of the image.
