Digital radiography is a form of radiography that uses x-ray–sensitive plates to directly capture data during examination, and immediately transferring it to a computer system without the use of an intermediate cassette. The advantages include time efficiency by bypassing chemical processing and the ability to digitally transfer and enhance images. Also, less radiation is needed to produce an image of similar contrast to conventional radiography.
In place of an X-ray film, digital radiography uses a digital image capture device. This offers multiple advantages: immediate image preview and availability; elimination of costly film processing steps; a wider dynamic range, which makes it more forgiving of over- and under-exposure; as well as the ability to apply special image processing techniques that enhance overall display quality of the image.
