For that reason, the x-ray movie is usually placed in between specially developed phosphorescent screens—panels composed of microscopic phosphorescent crystals embedded inside a plastic matrix that directs propagation in the phosphorescent mild toward the film.
A darkroom is just not needed for electronic impression capture, and that is now the common in veterinary radiography, so darkrooms will not be talked over. For information on darkroom procedures, you should see a text devoted to veterinary radiography.
