Digital radiography (DR) systems use active matrix flat panels consisting of a detection layer deposited over an active matrix array of thin film transistors and photodiodes. With DR the image is converted to digital data in real-time and is available for review within seconds.
What does Dr stand for in imaging?

DR Systems was founded in 1992 by two practicing neuroradiologists, Murray Reicher, M.D., and Evan K. Fram, M.D. The company delivered its first PACS product in January 1993.What is the primary difference between CR and DR?
DR uses flat panel detectors based on direct or indirect conversion of X-rays to charge, which is then processed to produce a digital image. CR uses cassette-based phosphor storage plates (PSP), which are then scanned by the computerized system into a digital format for image processing, archiving, and presentation.
