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.
roentgenotherapy, roentgentherapy
Radiotherapy, the treatment of disease by particle application, as of x-ray photons, nuclear disintegrations, or ultraviolet radiation.
stereoroentgenography, stereoradiography
Preparation of a pair of radiographs with an appropriate shift of the X-ray tube or film so that the images can be viewed stereoscopically to give a three-dimensional appearance.
teleroentgenography, teleradiography
1. Radiography in which the x-ray tube is placed some distance from the plate in order to minimize distortion.
2. Radiography with the X-ray tube positioned about two meters from the film thereby securing practical parallelism of the X-rays to minimize geometric distortion; the standard configuration for chest radiography.

teleroentgentherapy, teletherapy
Radiation therapy (treatment with high energy radiation from X-rays or other sources of radiation) administered with the source at a distance from the body.
