[Digital radiography: a new approach in roentgen diagnosis]

Digital electronics now play a role in every branch of diagnostic imaging. One of the most recent methods, digital radiography (DR) makes it possible to store and view radiographs in the form of a matrix of discrete values. The present review describes the components needed for DR imaging and archiving as well as the advantages and disadvantages of the system. The use of storage phosphor is hereby of special interest. By enableing the viewer to process the images, it is hoped that DR will open up new possibilities for projection radiography and strengthen its position as a routine method in comparison to other digital imaging systems, e.g. CT. It remains to be seen whether or not DR, as an isolated system, will be widely used. But in any case it represents the missing link in the chain of digital imaging methods and opens new ways of imaging archiving and administration.
