摘要 |
The invention relates, in a general way, to negatives obtained with the aid of photographic films, especially those used in X-ray radiology. The invention resides in a device for printing a sensitogram on each photographic negative of an object, the said negative being arranged in a cassette (10) containing a film (14) sensitive to the light radiation (RE), a scintillator screen (13) and a support foam (12). At each photograph, a defined portion (20) of the film is exposed directly, for a defined time, to light radiation (RE) of intensity calibrated by means of an open flap (trap) (18) and of a cut-out made in the support foam (12) and the scintillator screen (13). <IMAGE>
