Term | Definition |
---|---|
Acidifer | A chemical (acetic acid) in the fixer solution that neutralized the alkali in the developer solution and stops further action of the developer. |
Automatic Processor | A machine that develops, fixes, washes, and dries radiographic film. |
Developing Agent | Elon and hydroquinone, substances that reduce the halides in the film emulsion to metallic silver. |
Duplicating Film | A photographic film similar to x-ray films. |
Emulsion | The gelatinous coating on radiographic film containing silver halide crystals. |
Fixing Agent | It is one of several chemical ingredients in the fixer solution and functions to remove all unexposed and any remaining undeveloped silver bromide grains from the emulsion. |
Halide | Part of a halogen compound such as bromide and iodine that together with silver make up radiographic film emulsion. |
Identification Dot | Small circular embossed mark on the corner of the intra oral x-ray film. |
Intensifying Screen | Plastic sheet coated with calcium tungstate or rare earth fluorescent salt crystals. |
Latent Image | The invisible image produced when the film is exposed to x-ray photons. |
Occlusal Radiograph | Radiograph produced by placing the image receptor against the incised or occlusal plane. |
Oxidation | The process during which the chemicals of the developing and fixing solutions combine with oxygen and lose their strength. |
Pedodontic Film | Any smaller-sized film packet; phosphor plate, or digital sensor used for radiographs of children's teeth. |
Safelight | Special filtered light that can left on in the darkroom while films are processed. |
Selective Reduction | Chemical change that takes place within the film emulsion during development. |
Silver-halide crystals | Compounds of a halogen with silver, sensitive to radiation. |
