The article "Digitizing radiographic images is not very easy" / In the world of non-destructive testing 4 (54) December 2011 / The main limitations of radiography associated with the use of films are known: low productivity, small dynamic range, inconvenience of developing and storing results, increased energy and water consumption. The main disadvantage is the constant consumption of materials (silver, water, film, developer and fixer) due to the fact that the film is used only once. One of the most popular technologies to replace film with the required image quality is computed radiography (CR). This technology uses special, flexible, reusable plates for imaging instead of film. Cassettes with such plates have dimensions typical for X-ray film (18x24 cm, 18x30 cm, 24x30 cm, 35x43 cm), as well as analogs of roll films. For storing images, a layer with photostimulated memory was used - a complex chemical compound (for example, BaFBrxl1-x: Eu2 +). The image quality obtained with CR systems is classified according to the classes for NDT film systems.
