roentgeno-, roentgen- (German: radiation, "x-ray").

So called after its discoverer, a German physicist Wilhelm Konrad Roentgen [1845-1923], who discovered "roentgen" rays [x-rays]. in 1895; winner of the Nobel prize in physics in 1901.


orthoroentgenography:
A technique for producing radiographs showing the exact sizes of organs or bones by using a narrow beam of x-rays perpendicular to the plate or film.
roentgen:
A unit for describing the exposure dose of x-rays or gamma rays. One unit can liberate enough electrons and positrons to produce emissions of either charge of one electrostatic unit of electricity per 0.001293 g of air (the weight of 1 cm3 of dry air at 0 degrees Centigrade and at 760 mm Hg).
roentgenism:
A morbid condition induced by x-rays.
roentgenocardiogram:
Radiocardiogram, the record or film obtained during radiocardiography.
roentgenocinematography:
Moving picture photography of x-ray studies.
roentgenogram:
Radiograph, the film on which an image is produced by exposure to x-rays.
2. To make a radiograph.
roentgenography:
Radiography, the process of obtaining an image for diagnosis using a radiological modality.
roentgenologist:
Radiologist, a physician who uses x-rays or other sources of radiation for diagnosis and treatment.
roentgenology:
Radiology, the branch of medicine concerned with radioactive substaces, including x-rays, radioactive isotopes, and ionizing radiations, and the application of this information to prevention, diagnosis, and treatment of disease.
roentgenolucent:
Radiolucent, allowing x-rays to pass through. A dark area appears on the radiograph.
roentgenometer:
Radiometer, an instrument for measuring the intensity of radiation.
roentgenometry:
Radiometry, the measuring of the intensity of radiation.
roentgenopaque:
Radiopaque, impenetrable to x-rays or other forms of radiation. A light area appears on the radiograph.
roentgenoparent:
Radioparent, penetrable by radioactive rays.
roentgenoscope:
Radioscope, an instrument used for inspection and examination of the inner structures of the body by fluoroscopic procedures.
roentgenoscopy:
Radioscopy, the inspection and examination of the inner structure of the body by fluoroscopic procedures.
roentgenotherapy, roentgentherapy:
Radiotherapy, the treatment of disease by particle application, as of x-ray photons, nuclear disintegrations, or ultraviolet radiation.
teleroentgenography:
Teleradiography or radiography in which the x-ray tube is placed some distance from the plate in order to minimize distortion.
