UMD: Image digitization systems designed to convert analog images (e.g., from a television camera) to digital information, permitting immediate viewing of digital radiographic and fluoroscopic images. The stored images can be manipulated through subtraction, black-and-white reversal, and edge enhancement, and hard-copy films can be printed from digital storage. These systems are frequently used to upgrade existing radiographic/fluoroscopic systems, replacing film photo-spot cameras.
