| radiogold colloid | A radioactive isotope of gold emitting negative beta particles and gamma radiation, with a half-life of 2.7 days; formerly used for irradiation of closed serous cavities in the palliative treatment of ascites and pleural effusion due to metastatic malignancies, and for liver scans. Synonym: 198Au colloid, colloidal radioactive gold. (05 Mar 2000) |
| radiogram | An obsolete term for radiograph. Origin: radio-+ G. Gramma, something written (05 Mar 2000) |
| radiograph | <dentistry> Another name for an X-ray (08 Jan 1998) |
| radiographer | A nonmedically qualified person who assists the radiologist in imaging (diagnostic radiographer) or the radiotherapist in treatment (therapeutic radiographer). (16 Dec 1997) |
| radiographic image enhancement | Improvement in the quality of an X-ray image by use of an intensifying screen, tube, or filter and by optimum exposure techniques. Digital processing methods are often employed. (12 Dec 1998) |
| radiographic image interpretation, computer-assisted | Computer systems or networks designed to provide radiographic interpretive information. (12 Dec 1998) |
| radiographic magnification | Use of optic and geometric techniques to enhance radiographic image quality and interpretation. It includes use of microfocal X-ray tubes and intensifying fluoroscopic screens. (12 Dec 1998) |
| radiographic parallel line shadows | The images of bronchial walls, usually thickened; colloq., British. Synonym: radiographic parallel line shadows. (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) |

| radio frequency |
1. (Abbreviated RF.) The number of oscillations per second of the electric and magnetic fields in the radio portion of the electromagnetic spectrum, generally that portion between 10 4 and 10 12 Hz; specifically, the frequency of a given radio carrier wave. 2. In radio or radar, pertaining to a signal at the transmitted or received frequency, as opposed to a signal translated to a different frequency (IF signal) or detected (video signal).
