John Joly (/ ˈ dʒ oʊ l i /; 1 November 1857 – 8 December 1933) was an Irish geologist and physicist known for his development of radiotherapy in the treatment of cancer. He is also known for developing techniques to more accurately estimate the age of a geological period, based on radioactive elements present in minerals, the uranium–thorium dating.
1914: 'Dublin method' in radiation therapy discovered by John Joly. [49] 1926: Three-point linkage invented by Harry Ferguson. [50] 1927: "Variant colonies of staphylococcus aureus" discovered by Joseph Warwick Bigger and his students. [51] 1931: Drumm Battery Train invented by James J. Drumm. [52] Sudocrem invented by Dublin pharmacist Thomas ...
Megavoltage X-rays are produced by linear accelerators ("linacs") operating at voltages in excess of 1000 kV (1 MV) range, and therefore have an energy in the MeV range. The voltage in this case refers to the voltage used to accelerate electrons in the linear accelerator and indicates the maximum possible energy of the photons which are subsequently produced. [1]
A 200 kV orthovoltage X-ray tube used for radiation therapy, 1938. Orthovoltage X-ray machines are similar to diagnostic (radiography) X-ray machines, except that higher voltages are used and the X-ray tube is longer, to prevent the high voltages from arcing across the tube. ICD10 =
External beam radiation therapy (EBRT) is a form of radiotherapy that utilizes a high-energy collimated beam of ionizing radiation, from a source outside the body, to target and kill cancer cells. The radiotherapy beam is composed of particles, which are focussed in a particular direction of travel using collimators [ 1 ] .
There is a risk of radiation exposure to other individuals (women/children/fetus), anaphylaxis, neutropenia (low neutrophils), and thrombocytopenia (low platelet). Zevalin, another radioligand therapy that targets non-Hodgkin lymphoma CD20 ligand but using Yttrium-90 as the radioisotope, was FDA approved in 2002.
John Stoddard Cancer Center is a cancer care center located in Central Iowa. It was the first cancer center in that location. It was the first cancer center in that location. The John Stoddard Cancer Center is a part of Iowa Health-Des Moines , where a number of important treatment options and services originated.
Tomotherapy is a type of radiation therapy treatment machine. [1] [2] [3] In tomotherapy a thin radiation beam is modulated as it rotates around the patient, while they are moved through the bore of the machine. The name comes from the use of a strip-shaped beam, so that only one “slice” (Greek prefix “tomo-”) of the target is exposed ...
