Digital radiography is also called direct digital radiography. The difference between digital radiography and conventional radiography may be compared to that between the old cameras based on the use of films that have to be developed in a darkroom, and modern digital cameras.

With respect to physical principles, there is not much difference between digital and film radiography. Instead of using film to both detect and store image data, digital radiography uses digital detectors to produce a digital image, which is then stored separately on a digital medium. There are 4 steps in digital radiography: image generation, processing, archiving, and presentation.
