Digital
radiography is a form of X-ray imaging, where digital X-ray
sensors are used instead of traditional photographic film. Advantages
include time efficiency through bypassing chemical processing and the
ability to digitally transfer and enhance images. Also, less radiation can
be used to produce an image of similar contrast to conventional
radiography.
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 of
the image.
