The history of scientific research and the discovery of the x ray in radiography

the history of scientific research and the discovery of the x ray in radiography In the century since wilhelm conrad roentgen's discovery of the x-ray in 1895, radiology has advanced from a scientific curiosity to a medical necessity.

X-rays were discovered in late 1895 by wilhelm conrad röntgen, a professor of physics at the university of würzburg, germany [1] the ability of the new rays to image the bones within a living hand interested the general public for some six months. Science magazines such as new scientist, science & vie, and scientific american cater to the needs of a much wider readership and provide a non-technical summary of popular areas of research, including notable discoveries and advances in certain fields of research. Model, theory and evidence in the discovery of the only crick and watson’s well-known model and franklin’s x-ray diffraction pictures (the evidence) but also the scientific models and their function and relationship to theory and world the received view, dominated by works by nancy cartwright and morgan and morrison (1999), rather. He has authored several book chapters in the field of x-ray imaging, is editor-in-chief of an international scientific journal in medical physics, and has responsibilities in the publication committees of international scientific organizations in medical physics. The discovery of x-rays after reading this section you will be able to do the following: summarize how roentgen discovered the x-ray discuss the impact roentgen's discovery had on the world at that time (1895), and then compare it to the impact it still has today.

X-ray radiography: detects bone fractures, certain tumors and other abnormal masses, pneumonia, some types of injuries, calcifications, foreign objects, dental problems, etc mammography : a radiograph of the breast that is used for cancer detection and diagnosis.

Use of radiology and radiography in medical technologies is so commonplace nowadays, that we seldom think of how they came about tools such as the x-ray and ultrasound are used in everything from fixing broken limbs to looking at babies before they are born. Ct, radiography, and fluoroscopy all work on the same basic principle: an x-ray beam is passed through the body where a portion of the x-rays are either absorbed or scattered by the internal.

Discovery of x-ray beams wilhelm roentgen was already working on the effects of cathode rays during 1895, before he actually discovered x-rays his experiments involved the passing of electric current through gases at extremely low pressure. A week after his discovery, rontgen took an x-ray photograph of his wife's hand which clearly revealed her wedding ring and her bones the photograph electrified the general public and aroused great scientific interest in the new form of radiation. Extensive use of x-ray imaging during the second world war, and the advent of the digital computer and new imaging modalities like ultrasound and magnetic resonance imaging have combined to create an explosion of diagnostic imaging techniques in the past 25 years. This discovery made a huge impact on the scientific community scientists quickly began reconstructing the experiment and began conducting new areas of study on the ray even the general public took an immense interest in the x-ray.

It was difficult to use x-rays in medicine before 1913 due to the high amount of voltage necessary for adequate images, which would often result in the source x-ray tube breaking down in 1913, coolidge designed a high vacuum x-ray tube that could serve as an intense and reliable source. Radiography is an imaging technique using x-rays to view the internal form of an object to create the image, a beam of x-rays, a form of electromagnetic radiation, are produced by an x-ray generator and are projected toward the object a certain amount of x-ray is absorbed by the object, dependent on its density and structural composition. X-rays make up x-radiation, a form of electromagnetic radiationmost x-rays have a wavelength ranging from 001 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×10 16 hz to 3×10 19 hz) and energies in the range 100 ev to 100 kevx-ray wavelengths are shorter than those of uv rays and typically longer than those of gamma rays. Date of discovery quoted in glasser, o, wilhelm conrad röntgen and the early history of the roentgen rays, charles c thomas publisher, springfield (1934) [2] australasian radiography 32 1 (1988) 12-17.

Since the discovery of x rays by roentgen in 1895, a progression of reports containing recommendations to reduce the hazards from this invisible light have been published. 8, 9 this book is the first comprehensive collection of x-ray images taken in the 19 th century he also described the scientific basis behind the generation of these emissions and how they were. Early history of x rays by alexi assmus the discovery of x rays in 1895 was the beginning of a revolutionary change in our understanding of the physical world.

Find more x-rays in the x-ray gallery try to imagine how different life would be without modern medical technology in 1895, the invention of the x-ray created an amazing step forward in the history of medicine. The ‘x-ray spectrometer’, a technology that would become invaluable in the science of x-ray crystallography, was designed by william h bragg and constructed at leeds university in 1913 by jenkinson, his instrument maker.

The x-ray was invented in 1895 by wilhelm conrad roentgen it all started with a vacuum tube called a crookes tube, with this roentgen noticed that by pressing a button that activated an electric current through it a shadow was projected onto a screen that showed the. The timeline below shows the date of publication of possible major scientific theories and discoveries, along with the discoverer in many cases, the discoveries spanned several years. The contribution of physics to the development of x-ray diagnosis was vital in the early years of this century following rontgen's discovery of x-rays in november 1895 this review records some of the highlights during the period 1895-1915. An x-ray is a two-dimensional picture and a cat-scan is three-dimensional by imaging and looking at several three-dimensional slices of a body (like slices of bread) a doctor could not only tell if a tumor is present but roughly how deep it is in the body.
