Since the shift away from screen-film radiography, imaging facilities have two basic choices for digital radiography systems: computed radiography (CR) or digital radiography (DR). With ongoing technological advancements and the significant reduction in price, DR is rapidly becoming the preferred choice.

Digital radiography image Computed radiography (CR) cassettes use photo-stimulated luminescence screens to capture the X-ray image, instead of traditional X-ray film. The CR cassette goes into a reader to convert the data into a digital image. 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.

While both CR and DR have a wider dose range and can be post proce...
