| 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) |
|---|---|
| radiography, interventional | Diagnostic and therapeutic procedures that are invasive or surgical in nature, and require the expertise of a specially trained radiologist. In general, they are more invasive than diagnostic imaging but less invasive than major surgery. They often involve catheterization, fluoroscopy, or computed tomography. Some examples include percutaneous transhepatic cholangiography, percutaneous transthoracic biopsy, balloon angioplasty, and arterial embolization. (12 Dec 1998) |
| radiography, panoramic | Extraoral body-section radiography depicting an entire maxilla, or both maxilla and mandible, on a single film. (12 Dec 1998) |
| radiography, thoracic | X-ray visualization of the chest and organs of the thoracic cavity. It is not restricted to visualization of the lungs. (12 Dec 1998) |
| magnification radiography | Radiography using a microfocal X-ray tube and increased subject-film distance to provide geometric magnification of the subject without unacceptable loss of sharpness and resolution or an undesirable increase in radiation exposure caused by increasing the distance between the subject and the film. (05 Mar 2000) |
| computed radiography | Radiography using a solid-state imaging device, such as a photostimulable phosphorplate, and recovering, enhancing, and displaying the image using a digital computer. (05 Mar 2000) |
| mucosal relief radiography | Radiographic technique showing fine detail of gastrointestinal mucosa after coating it with a barium suspension and distending the organ with air or gas released from an ingested powder. (05 Mar 2000) |
| portable 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) |
| scanning equalization radiography | An electronically enhanced method of radiography in which a small X-ray beam is scanned over the patient while its attenuation is measured, providing feedback to modulate beam intensity in order to equalise average X-ray film exposure. (05 Mar 2000) |
| sectional radiography | <procedure, radiology> The recording of internal body images at a predetermined plane by means of the tomograph, also called body section roentgenography. Origin: Gr. Graphein = to write (18 Nov 1997) |
| spot-film radiography | An X-ray of a localised region, usually under study by fluoroscopy. (05 Mar 2000) |
| digital radiography | Computed radiography or computer processing of a digitised image from a conventional image-intensifier and video camera. See: DSA. (05 Mar 2000) |
| electron radiography | <radiology> Radiographic imaging in which X-radiation incident on the receptor is converted to a latent charge image and subsequently recovered by a special printing process; advantages include wider latitude of exposure and greater sensitivity than conventional film-screen combinations. See: xeroradiography, phosphor plate. (05 Mar 2000) |
