The Science of Radiology and Radiologic Technology Flashcards
A radiograph of the hand taken by Roentgen in
December 1895
Discovered X-Ray (Nov 8, 1895)
His wife Anna bertha Ludwig
December 1895
Wilhelm Conrad Roentgen
demonstrated to the French academy of science that x-rays were released when cathode struck the wall gas discharge tube.
Henri Poincare
Discovered that potassium uranyl sulfate spontaneously emitted type of radiation that he termed becquerel rays, now popular known as β Particles (Beta particles)
Henri Becquerel
Marie Curie explored Becquerel rays her doctoral thesis and chemically separated a number of elements she discovered the radioactive properties of naturally occurring blank, blank, and blank all of which emit α particles (Alpha Particles)
thorium, radium, and polonium
He reported in 1897 that cathode rays used to produced X-rays were negatively charged particles (i.e electrons) with about 1/2000 the mass of the hydrogen atom. Within five years of the discovery of X-rays, Electrons and natural radioactivity had also been identified.
J.J Thompson
Blank advanced with the help improvements such as intensifying screens, hot-cathode X-ray tubes, rotating anodes, image intensifiers and contrast agents.
X-ray imaging
What decade did the diagnostic imaging progressed as a symbiosis of X-ray imaging with the emerging specialties of nuclear medicine and ultrasonography.
1950’s and 1960’s
It enables image formation for various modalities of medical imaging X-ray, Nuclear imaging, magnetic resonance imaging (MRI) and ultrasonography (US) and many others.
Medical Imaging
He used to large, partially evacuated glass tube that encompassed a cathode and an anode attached to an electrical supply.
His tube was the early version of the modern fluorescent light.
Sir William Crookes (1832—1919)
The date of the blank is believed by historians to be the day that Rontgen created the famous image of his wife’s hands.
November 8, 1895
Rontgen submitted his 1st report, titled on a new kind ray, to the Wurzburg Physio-Medical Society.
December 28, 1895
Rontgen was Honored in 1901 with the 1st Nobel Prize in Physics. He died in blank colon cancer
February 10, 1923
It came into use for both imaging (nuclear Medicine) and treatment. By the 1970’s imaging had further advance to include diagnostic medical sonography, computed tomography (CT) and MRI.
Radiation Substances
He discovered X-Ray (Nov. 8, 1895)
Wilhelm Conrad Roentgen
He developed fluoroscope using calcium tungstate in1896
Thomas A. Edison
He discovered radioactive with uranium element 1896.
Antoine Henri Becquerel
They discovered radioactive element radium in 1898
Marie and Pierre Curie
He became the 1st X-ray fatality who died in cancer in 1904
Clarence Dally
He develop mammography in 1913
Albert Solomon
He develop cerebral angiography in 1927
Egas Moniz
He performed the 1st heart catheterization on himself in 1929
Werner Forssman
They discovered the artificially produced radioisotopes in 1934
Frederic and Irene Joliot Curie
They introduced the 1st diagnostic cardiac catheterization in 1940
Andre Cournand and Dickinson Richards
He introduced the modern mammography in 1950
Robert Egan
He invents fetal Ultrasound in 1957
Ian Donald
Introduced the selective coronary angiography in 1960
Mason Sones
They developed the single Photon Emission Computed Tomography (SPECT) in 1963
David Kuhl and Roy Edwards
He Introduced Image- Guided Intervention in 1964.
Charles Dotter
In what year did Godfrey Hounsfield developed CT scanner with Allan Cormack as Co-developer
1972
He Invented the 1st MR (Magnetic Resonance) scanning machine or MRI in 1977.
Raymond D. Damian
In what year is the Introduction of computed Radiography by FUJI
1987
In 2007 Direct Radiography or Digital Radiography was developed by
Eastman Kodak/ Carestream
