ABSTRACT:
Method and apparatus for marking a film with information, e.g. patient data and other possible information in X-ray photography, such as panoramic tomography. The X-ray beam creating the X-ray photograph, and the X-ray film move in a certain manner in relation to one another. A certain area of the film is reserved for markings which are latently made thereon, to become visible when the X-ray film is developed. Markings are made simultaneously with the film exposure to the X-ray beam for the X-ray photography. The markings are sequentially made by using relative movement of the radiation with which the marking is made upon the film and the film itself, such relative movement being synchronized with the relative movement of the X-ray beam to which the film is exposed for the actual X-ray photography, and the film itself, the relative movement preferably representing a parallel deflection or displacement along a marking row.
