<p>Method and apparatus for marking a film with patient data and possible other information in panoramic tomography X-ray photography. In the method the X-ray beam (X) creating the X-ray photograph and the X-ray film (F) move in a certain way in relation to each other. A certain area (Fy) of the film (F) is reserved for markings made with the method, which markings are made latent on the film to become visible when the X-ray film is (F) developed. Markings are made simultaneously with the film (F) exposure to an X-ray beam (X) for X-ray photography. The markings are made as a sequence by using, as the deflection parallel with the marking row, the relative movement of the radiation (X; L) with which the marking is made on the film and the film (F) itself, which movement is synchronized with the relative movement of the X-ray beam (X), to which the film is exposed for actual X-ray photography, and the film (F) itself. </p> |
