Abstract
An arrangement for the light-projection of indicia from a data carrier onto an X-ray film which is located in an X-ray film cassette having a light-sealed closable window, by means of an installation incorporating means for the opening of the window of the X-ray film cassette upon the latter being inserted into the installation, a light source for illuminating the data carrier which is inserted into the installation, an optical device for projecting the data of the data carrier through the opened window of the X-ray film cassette onto the X-ray film located in the X-ray film cassette, and switch means for commencing the light exposure and projection. In the arrangement of the above-mentioned type, a so-called "dove prism" is interposable in the optical beam path of the data being projected through the use of setting means, for the correct non-reversed transillumination or projection of the data for posterior anterior, as well as for anterior posterior exposures.
