WebFeb 22, 2024 · To render the latent image visible, the IP is inserted into a CR image reader, where it is scanned by a laser beam. This process forces the trapped electrons in the conduction band to return to the valence band, thus creating a bluish-purple light. Such emission is called photostimulable luminescence. WebDec 26, 2024 · The X-ray film consists of the protective layer, emulsion, adhesive, and polymer substrate. The substrate is coated with a thick layer of photosensitive emulsion on both sides to increase the X-ray absorption for mitigating blurring. Typically, the emulsion layer is made of innumerable silver-halide compounds mixed with gelatin material [ 26, 27 ].
