| cephalometric analysis | A study of the skeletal and dental relationships used in orthodontic case analysis. (05 Mar 2000) |
|---|---|
| cephalometric radiograph | A radiographic view of the jaws and skull permitting measurement. Synonym: cephalogram. (05 Mar 2000) |
| cephalometric tracing | <dentistry> An overlay drawing traced over a cephalometric X-ray that shows specific structures and landmarks that provided a basis for orthodontic therapy. (08 Jan 1998) |
| cephalometric viewer | <dentistry> An X-ray viewer (08 Jan 1998) |
| cephalometric X-rays | <dentistry> An X-ray of the head that shows whether your teeth are aligned properly, and whether they are growing properly. (08 Jan 1998) |
| tracing (cephalometric) | <dentistry> An overlay drawing traced over a cephalometric X-ray that shows specific structures and landmarks that provided a basis for orthodontic therapy. (05 Mar 2000) |
| advanced multiple-beam equalization radiography | A variant of scanning equalization radiography using several X-ray beams. (05 Mar 2000) |
| air-gap radiography | Chest radiography with a space (at least 10 inches) between the subject and film. Instead of using a grid, this method uses the geometry and X-ray absorption by the air to remove scattered radiation. (05 Mar 2000) |
| bedside radiography | Making radiographic films of a patient confined to bed by taking a movable X-ray machine to the room. Synonym: bedside radiography. (05 Mar 2000) |
| radiography | <investigation, procedure> The making of film records (radiographs) of internal structures of the body by passage of X-rays or gamma rays through the body to act on specially sensitised film. Origin: Gr. Graphein = to write (18 Nov 1997) |
| radiography, abdominal | Radiographic visualization of the body between the thorax and the pelvis, i.e., within the peritoneal cavity. (12 Dec 1998) |
| radiography, bitewing | Technique involving the passage of X-rays through oral structures to create a film record while a central tab or wing of dental X-ray film is being held between upper and lower teeth. (12 Dec 1998) |
| radiography, dental | Radiographic techniques used in dentistry. (12 Dec 1998) |
| radiography, dental, digital | A rapid, low-dose, digital imaging system using a small intraoral sensor instead of radiographic film, an intensifying screen, and a charge-coupled device. It presents the possibility of reduced patient exposure and minimal distortion, although resolution and latitude are inferior to standard dental radiography. A receiver is placed in the mouth, routing signals to a computer which images the signals on a screen or in print. It includes digitizing from X-ray film or any other detector. (12 Dec 1998) |
| radiography, dual-energy scanned projection | A method of producing a high-quality scan by digitizing and subtracting the images produced by high- and low-energy X-rays. (12 Dec 1998) |
