Blood irradiation therapy is an alternative medical procedure in which the blood is exposed to low-level light (often laser light) for therapeutic reasons. [1] The practice was originally developed in the United States, [ 1 ] but most recent research on it has been conducted in Germany (by UV lamps ) and in Russia (in all variants).
Total body irradiation (TBI) is a radiation therapy technique used to prepare the body to receive a bone marrow transplant. Brachytherapy , in which a radioactive source is placed inside or next to the area requiring treatment, is another form of radiation therapy that minimizes exposure to healthy tissue during procedures to treat cancers of ...
Proton therapy. In medicine, proton therapy, or proton radiotherapy, is a type of particle therapy that uses a beam of protons to irradiate diseased tissue, most often to treat cancer. The chief advantage of proton therapy over other types of external beam radiotherapy is that the dose of protons is deposited over a narrow range of depth; hence ...
Irradiation. Irradiation is the process by which an object is exposed to radiation. An irradiator is a device used to expose an object to radiation, notably gamma radiation, for a variety of purposes. [1] Irradiators may be used for sterilizing medical and pharmaceutical supplies, preserving foodstuffs, alteration of gemstone colors, studying ...
Radiation oncologist. A radiation therapist, therapeutic radiographer or radiotherapist is an allied health professional who works in the field of radiation oncology. Radiation therapists plan and administer radiation treatments to cancer patients in most Western countries including the United Kingdom, Australia, most European countries, and ...
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. A radiotherapy beam is composed of particles which travel in a consistent direction; each radiotherapy beam consists of one type of particle intended ...
The rad is a unit of absorbed radiation dose, defined as 1 rad = 0.01 Gy = 0.01 J/kg. [1] It was originally defined in CGS units in 1953 as the dose causing 100 ergs of energy to be absorbed by one gram of matter. The material absorbing the radiation can be human tissue, air, water, or any other substance.
Prophylactic cranial irradiation (PCI) is a technique used to combat the occurrence of metastasis to the brain in highly aggressive cancers that commonly metastasize to brain, most notably small-cell lung cancer. [1] Radiation therapy is commonly used to treat known tumor occurrence in the brain, either with highly precise stereotactic ...
