What Is a Digital Mammogram?

Digital radiography (DR) is also a new digital imaging technology recently developed. It has similar uses to computer radiography (CR), but the basic principles and structures are different. DR is developed on the basis of digital fluorography (DF). It uses an image enhancement tube as an information carrier, accepts X-ray information passing through the human body, collects it by a video camera, converts it to a digital signal, and digitizes it. Different from CR, except for the difference of the information carrier, it does not match with other equipment and requires special equipment. CR can use an imaging board to collect information on any X-ray imaging equipment. DR, like CR, can perform various post-processing of images, and can transfer and store images.
