What is digital radiography?
Digital radiography is a system where the x-ray image is stored not on film but as a matrix of numbers, each representing the amount of radiation reaching a detecting system. These systems use detectors that are more efficient than conventional film and this leads to a reduction in x-ray dose to the patient. Information captured in this manner can be stored and used in electronic systems such as computers. There are two main types of technology available to capture digital radiography images, CCD (charged-coupled device) powered sensors and photostimulable phosphor (PSP) plates.
