Historical Development Flashcards
It is a modality used for the treatment of CANCER
RADIATION ONCOLOGY OR RADIATION
THERAPY
Father of medicine; used the terms “carcinos and carcinoma” to describe non-ulcer forming and ulcer-forming tumors.
HIPPOCRATES (460 - 370 BC)
The Greek word ______ means _______.
“Karkinos”, Crab
The accidental discovery of x-ray by Wilhelm Conrad Roentgen
NOVEMBER 8, 1895
Roentgen took the very first radiograph of his wife’s hand with a ring.
DECEMBER 26, 1895
Irradiated a female patient named “Rose Lee” due to locally advanced left breast cancer.
He became the world’s first radiation
oncologist.
1896 , DR. EMILE H. GRUBBE
He discovered natural radioactivity from
Uranium Salts.
His discovery made him as “Father of
Radioactivity”.
Old term “Becquerel” unit.
1896, ANTOINE HENRI BECQUEREL
1st physician to use ionizing radiation for
treatment purposes.
He irradiated hairy moles of a 5-year old
He also published the 1st textbook on
radiation therapy in 1903.
1896 LEOPOLD FREUND
They both discovered Polonium and
Radium
Discovery of Radium
New Term of Radioactivity “Curie”
1898, MARIE AND PIERRE CURIE
They postulated the first law of
radiosensitivity
1906
- JEAN ALBAN BERGONIE AND LOUIS
TRIBONDEAU
The first LINAC was constructed by him.
The principles of LINAC was proposed by
Gustav Ising in 1924.
WOLF WIDEROE 1928
They both recognized that treatment may be
better tolerated and more effective if delivered
more slowly with modest doses per day over
several weeks.
Fractionated (smaller doses rather than single
large dose) could achieve the same tumor response
without serious injury to adjacent normal tissue.
1930, CLAUDIUS REGAUD AND HENRI COUTARD
He discovered neutron on which inspired
the U.S. government to begin serious
atomic bomb research efforts.
1932, JAMES CHADWICK
They discovered the first-ever artificially created radioactive atoms (Artificial
Radioactivity).
1934, IRÈNE AND FRÉDÉRIC JOLIOT-CURIE
He invented the cyclotron.
He is known for his work on uranium-isotope
separation.
He was intrigued by a diagram of an accelerator that
produced high-energy particles and contemplated that it could be made compact and came up with an idea for a circular accelerating chamber between the poles of an electromagnet. Hence, the result was the first cyclotron.
1939, ERNEST ORLANDO LAWRENCE
