Digital radiography (DR) may be a form of x-ray inspection that generates a digital radiographic image on a computer in real time. During object examination, x-ray sensitive plates capture data, which is then instantaneously sent to a computer without the necessity of an intermediate cassette. A detector sensor converts the incident x-ray radiation into a similar charge, which is then transformed into a digital image.


Flat panel detectors, commonly called digital detector arrays (DDAs), deliver high-quality digital images as compared to traditional imaging equipment. They will have the next ratio and a wider dynamic range, leading to increased sensitivity for radiography applications. Indirect conversion and direct conversion are the 2 methods employed by flat panel detectors. Indirect conversion flat panel detectors use a scintillator layer to convert x-ray photons to light photons, which are then converted into an electrical charge by an amorphous silicon photo diode matrix. the number and energy of x-ray photons interacting with the detector pixel, and thus the quantity and density of fabric that has absorbed the x-rays, are proportional to the current charge.
