Abstract

A system for recording information on a film medium sensitive to X-rays, without disturbing the radiographic image previously recorded on the same film. The system includes a set of adjacent X-rays sources and a source control which sequentially controls the X-rays emitted by each source. Different printing levels on the medium are obtained by controlling X-ray output dosage by each source.
