Study Notes
Radiologic Technologists
- Assist radiologists during specialized contrast media procedures like myelography and arthrography.
- Complete academic requirements in Associate in Radiologic Technology and Bachelor of Science in Radiologic Technology (BSRT) to become a registered radiographer.
Registered Radiologic Technologist
- Abbreviation: RXT or RRT.
- Recognized by the Professional Regulation Commission (PRC).
Ionizing and Non-ionizing Radiation
Discovery of X-Rays
- November 8, 1895, by Wilhelm Conrad Roentgen, a German physicist.
- Experimenting with cathode rays and properties outside glass tubes (Crooke's Tube) at the University of Wurzburg, Germany.
- Observed that a screen painted with barium platinocyanide was emitting light (fluorescence) when brought close to the tube.
Characteristics of X-Ray Discovery
- Accidental discovery.
- Contemporaries of Roentgen had observed x-radiation but did not recognize its significance.
- Roentgen investigated it with scientific vigor, describing x-radiation with nearly all its properties within a month.
Pioneers of Radiology
- William Crookes: furthered the study of cathode rays and demonstrated that matter was emitted from the cathode with enough energy to rotate a wheel.
- Philipp Lenard: investigated cathode rays, finding they could penetrate thin metal and project into air, and studied deflection as a result of magnetic fields.
- William Goodspeed: produced a radiograph in 1890, but was not credited with the discovery of x-rays.
- Richard Leach Maddox: produced a film with a gelatin silver bromide emulsion.
- George Eastman: produced and patented roll-paper film.
Wilhelm Conrad Roentgen
- Born on March 27, 1845, in Lennep, Germany.
- Married Bertha Ludwig in 1872.
- Worked at the University of Wurzburg, where he discovered x-rays.
Early X-Ray Images
- First medical x-ray image in the United States was taken from a patient who broke his wrist skating on the Connecticut River.
