During the last two decades medical imaging has moved more and more toward digital technology. At one hand, digital imaging has become a widely used replacement for conventional film in radiography (see Chapters 21 and 22, computed radiography and digital fluoroscopy), at the other hand the primarily digital cross sectional modalities contribute an ever increasing part of medical imaging.
