Abstract

A method and a reading station for processing a cassette containing an X-ray film coated with a layer of stimulatable phosphorus are proposed. The cassette with the film therein, before being positioned in the reading station, is exposed to X-rays to produce a latent image thereon. The film is then removed from the cassette and the phosphorus layer is brought by a laser beam scanner to luminescence so that the emitted light converts the latent image into digital electric signals stored in the central memory. The film is then erased and re-inserted into the same cassette within the reading station.
