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)
