| 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) |
| serial radiography | Making several X-ray exposures of a single region over a period of time, as in angiography. (05 Mar 2000) |
| 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) |
| abdominal part of thoracic duct | The part of the thoracic duct between the cisterna chyli and the aortic hiatus of the diaphragm. Synonym: pars abdominalis ductus thoracici. (05 Mar 2000) |
| anterior intercostal branches of internal thoracic artery | One of the arteries supplying the anterior portions of the intercostal spaces of the thoracic wall. Anterior intercostal arteries 1-6 arise as branches of the internal thoracic artery; 7-11 arise as branches of the musculophrenic artery. Synonym: rami intercostales anteriores, rami intercostalis anteriores arteria thoracica interna. (05 Mar 2000) |
| aorta, thoracic | The portion of the descending aorta proceeding from the arch of the aorta and extending to the diaphragm. (12 Dec 1998) |
| aortic aneurysm, thoracic | An aneurysm in the proximal portion of the descending aorta proceeding from the arch of the aorta and giving rise to the bronchial, oesophageal, pericardiac, and mediastinal branches. (12 Dec 1998) |
| arch of thoracic duct | See: thoracic duct. (05 Mar 2000) |
| arterial thoracic outlet syndrome | <syndrome> A rare disorder due to compression of the subclavian artery (with resultant poststenotic dilation) by a fully formed cervical rib; thrombi form in the dilated distal arterial segment, and distal limb ischemia may occur due to thromboembolic events. (05 Mar 2000) |
| asphyxiating thoracic chondrodystrophy | Hereditary hypoplasia of the thorax, associated with pelvic skeletal abnormality. Synonym: asphyxiating thoracic chondrodystrophy, Jeune's syndrome, thoracic-pelvic-phalangeal dystrophy. (05 Mar 2000) |
| asphyxiating thoracic dysplasia | Hereditary hypoplasia of the thorax, associated with pelvic skeletal abnormality. Synonym: asphyxiating thoracic chondrodystrophy, Jeune's syndrome, thoracic-pelvic-phalangeal dystrophy. (05 Mar 2000) |
