General Terms Radiology: Radiology is the science and application of roentgen rays, radium rays, or other high frequency rays. Radiologist: A radiologist is a medical specialist in employing roentgen rays and/or radio-active substances. Roentgenology: Roentgenology is the diagnostic application of roentgen rays. Roentgenography (Radiography): Roentgenography is the art of producing radiographs. Radiation: Radiation is the radiant energy emitted by an X-ray tube, by radioactive substances, or by other sources. Roentgenogram (Skiagraph,* Skiagram*): A roentgenogram is a photographic record of the relative transparency of the various parts of an object to roentgen rays. Radiograph (Radiogram*): Radiograph is a record produced on a photographic plate, film, or paper by the action of roentgen rays or radium. Fluoroscopy: Fluoroscopy is the use in diagnosis, testing, etc., of a fluorescent screen which is activated by roentgen rays.
