[Microdocumentation of x-ray film via the "linear system" (author's transl)].

The new Federal German Roentgen Law in operation for the last two years governs not only the proprietary rights in respect of x-ray documentation but also the obligation regarding its accountability. Similar regulations are in preparation in other European countries. Since the discussions on individual problems of maintaining and cataloguing x-ray films and on approaches towards solving the production of duplicates, are common knowledge, there is no need to go into them once again, not lease because of their complex nature. Nevertheless, these problems are touched upon in the present article in the manner of key words in order to illustrate to what extent the Linear System meets the requisite demands.
