- Students will be able to describe the work of Marie and Pierre Curie in radioactivity.
- Students will be able to list the events leading to the development of nuclear medicine.
- Students will be able to describe the modern radiology department, including equipment, tasks, and staff development through continuing education.
The Pioneers of Radiology
- Early scientists and craftworkers enabled the production of X-rays.
- Key scientific advancements paving the way for X-ray discovery include electricity, vacuums, and image recording materials.
Early Scientists and Inventors
- Evangelista Torricelli invented the barometer in 1643.
- Otto von Guericke invented an air pump.
- Robert Boyle and Herman Sprengel improved vacuum techniques.
- William Gilbert studied electricity and magnetism.
- Isaac Newton improved static generators.
- Charles DuFay categorized different types of electricity.
- Abbe Jean Nollet made improvements in the electroscope.
Further Development of Cathode Rays
- William Watson transmitted electricity through wires and vacuum tubes.
- William Morgan observed coloration changes in partially evacuated tubes.
- Michael Faraday's experiments led to electromagnetic induction and better generators.
- John Wilhelm Hittorf experimented with cathode rays.
- William Crookes further explored cathode rays and their ability to turn wheels within tubes.
- Philipp Lenard researched cathode ray penetration of metals and measured their energy.
- William Goodspeed created a radiograph.
Image Recording Techniques
- J.H. Scholtz produced the first photographic copy of written material (1727).
- R.L. Maddox created film with gelatin silver bromide emulsion (1871).
- George Eastman invented roll film (1884).
Wilhelm Conrad Roentgen
- Born in Lennep, Germany (March 27, 1845).
- Married Bertha Ludwig in 1872.
- Received an offer from the University of Würzburg in 1888.
- Became interested in cathode ray experiments using Crookes tubes.
Discovery of X-rays
- On November 8, 1895, Roentgen observed fluorescence on a barium platinocyanide paper near a Crookes tube.
- Roentgen realized this was a new type of ray, rather than light or electricity, escaping the Crookes tube.
- Roentgen's subsequent experiments demonstrated the rays' ability to penetrate materials and dependence on material density.
- On December 28, 1895, Roentgen presented his findings to the Würzburg Physico-Medical Society.
Medical Use of X-rays
- Roentgen recognized the potential medical applications of X-rays.
- Roentgen demonstrated bone visualization using his own hand as an example.
- Further experiments validated the validity of his findings.
Roentgen's Recognition and Later Life
- Roentgen received the Nobel Prize in Physics in 1901.
- Received an invitation from the Carnegie Institute in 1902 but did not accept.
- Died in Munich on February 10, 1923.
Marie and Pierre Curie
- Marie Curie discovered radium and polonium.
- The Curies developed treatments for cancer.
- In WWI, the Curies supported wounded soldiers by providing mobile radiology units.
- Marie Curie was a two-time Nobel Prize winner and a pioneer for women.
- The Curies used their understanding of radioactivity to design instruments to measure radiation (no matter form).
Nuclear Radiology
- Continuous improvements in X-ray equipment continued after Roentgen's discovery.
- Ernest Lawrence's invention of the cyclotron (1932) allowed for the acceleration of particles for use as projectiles.
- Enrico Fermi (1942) produced a chain reaction in a uranium pile at the University of Chicago.
Modern Radiology
- The advancements in radiology have been remarkable.
- Diagnostic and therapeutic equipment includes CT scanning, nuclear medicine, radiation therapy.
- Specialized areas of radiology exist today including ultrasound, neurovascular radiology, digital vascular imaging for IV angiography
Summary
- Advanced equipment produces multiple exposures precisely in contemporary radiology departments.
- Continuous education remains essential to keep up with evolving technologies
