title: [Film-less digital x-ray image processing--new prospects with the RadioVisioGraphy equipment].
abstract: Due to a new removable and compatible mass storage media, the ultimate model of the RadioVisioGraphy (RVG) system for X-ray recording without films offers an adequate possibility to store images as well as an easy way to transfer these data to other personal computers for digital image processing. By experiment we demonstrated a digital image subtraction procedure with public domain software, simulating a situation before and after apicoectomy. The result shows a good quality with a favourable relation between signal and noise.
