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.
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.
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).
A morbid condition induced by x-rays.
Radiocardiogram, the record or film obtained during radiocardiography.
Moving picture photography of x-ray studies.
Radiograph, the film on which an image is produced by exposure to x-rays.
2. To make a radiograph.
Radiography, the process of obtaining an image for diagnosis using a radiological modality.
Radiologist, a physician who uses x-rays or other sources of radiation for diagnosis and treatment.
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.
Radiolucent, allowing x-rays to pass through. A dark area appears on the radiograph.
Radiometer, an instrument for measuring the intensity of radiation.
Radiometry, the measuring of the intensity of radiation.
Radiopaque, impenetrable to x-rays or other forms of radiation. A light area appears on the radiograph.
Radioparent, penetrable by radioactive rays.
Radioscope, an instrument used for inspection and examination of the inner structures of the body by fluoroscopic procedures.
Radioscopy, the inspection and examination of the inner structure of the body by fluoroscopic procedures.
Radiotherapy, the treatment of disease by particle application, as of x-ray photons, nuclear disintegrations, or ultraviolet radiation.
Teleradiography or radiography in which the x-ray tube is placed some distance from the plate in order to minimize distortion.
