---|---|
Automatic Processor | Machine that automates all film processing steps |
Beam alignment device | Assists in the positioning of the position indicator device (PID). |
Bitewing | Image view that shows the crowns of both arches on one film. |
Calcium tungstate | Common type of phosphor. |
Cassette | Contains extraoral films during exposure |
Cephalometric film | Shows the bony and soft tissue areas of the facial profile. |
Charge-coupled device (CCD) | A solid-state image sensor used in intraoral digital imaging. |
Digital image | Electronic signals captured by sensors and displayed on computer monitors. |
Digitize | Scanning of traditional film-based radiographs into a digital image. |
Duplicating film | Film designed for use in film duplicating machines |
Emulsion (ee-MUL-shun) | A coating on the x-rays film that contains energy sensitive crystals |
Extraoral film | Film designed for use in cassettes |
Films speed | The sensitivity of the emulsion on the film to radiation |
Intensifying screen | The part inside an extraoral cassette that converts x-ray energy into visible light, which in turn exposes screen film |
Label side | Colored side of the film that faces the tongue |
Latent image | The invisible image on the x-ray film after exposure but before processing |
Occlusal | Radiographic view that shows large areas of the maxilla or mandible |
Panoramic Film | Used in cassettes to provide a wide view of both the upper and lower jaw |
Periapical (per-ee-AP-i-kul) | Radiographic view that shows the crown, root tip, and surrounding structure |
Phosphor storage plate (PSP) | Reusable film-sized plate plates coated with phosphor as the image receptor |
Positioning instruments | intraoral devices used to position and hold the film, sensor, or PSP |
Processing | a series of steps that change exposed film into a radiograph. Steps include developing, rinsing, fixing, washing, and drying |
Radiograph | image produced on photosensitive film by expoing the film to radiation and then processing it |
