In the United States, the first medical X-ray with a discharge tube was obtained from Ivan Pulyui. In January 1896, while reading Röntgen`s discovery, Frank Austin of Dartmouth College tested all the discharge tubes in the physics laboratory and discovered that only pulyui`s tube produced X-rays. This was the result of Pulyui`s recording of an oblique mica “target” used to retain samples of fluorescent material in the tube. On February 3, 1896, Gilman Frost, a professor of medicine at the college, and his brother Edwin Frost, a professor of physics, exposed the wrist of Eddie McCarthy, whom Gilman had treated for a fracture a few weeks earlier, to X-rays and collected the resulting image of the broken bone on photo plates of gelatin obtained by Howard Langill. a local photographer who was also interested in Röntgen`s work. [12] Radiology technicians (فني اشعة) in Saudi Arabia must successfully complete a degree in nursing at a recognized higher education institution before continuing their studies in X-ray imaging at the university for typically 2-3 years; this must include one year of experience in a hospital. In the end, graduates are qualified radiology technicians and can begin clinical practice. [56] The origins of radiography and fluoroscopy date back to November 8, 1895, when German physics professor Wilhelm Röntgen discovered X-rays and discovered that they could pass through human tissue, but not bone or metal. [5] X-rays called “X-ray” radiation to indicate that it was an unknown type of radiation. For his discovery, he was awarded the first Nobel Prize in Physics. [6] A new and evolving career for radiology technologists is that of Certified Radiologist Assistant (R.R.A.) [71] who is an experienced technologist (a kind of physician assistant) who has undergon additional training and training and has passed examinations as a radiologist. [72] [73] A list of the 9 currently accredited R.R.A.
programs is maintained by arrT and can be consulted online. [74] Candidates for the R.R.A. The certification must have at least a Bachelor of Science degree.
