Direct digital radiography definition
Direct digital radiography or “DDR” (also see CR and DR) means an X- ray imaging method in which a digital sensor, usually incorporating a thin- film transistor, is used to capture an X-ray image. Some DDR systems use a scintillator to convert X-rays to light and a photodiode array to convert light to charge, while others use a photoconductor to convert X-rays directly to charge, which is stored on the thin-film transistor.
