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 ]
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 ...
These substances may include ligands of receptors present on the target tissue or compounds, like iodine, that are internalized by the target through metabolic processes. By using these mechanisms, theranostics enables the localization of pathological tissues with imaging and the targeted destruction of these tissues using high doses of radiation .
This is a type of targeted therapy which uses the physical, chemical and biological properties of the radiopharmaceutical to target areas of the body for radiation treatment. [3] The related diagnostic modality of nuclear medicine employs the same principles but uses different types or quantities of radiopharmaceuticals in order to image or ...
Targeted intra-operative radiotherapy, also known as targeted IORT, is a technique of giving radiotherapy to the tissues surrounding a cancer after its surgical removal, a form of intraoperative radiation therapy. The technique was designed in 1998 at the University College London.
Accurate, real time dosimetry to better estimate the radiation doses delivered to the tumor and normal tissues in patients with brain tumors and head and neck cancer. Further clinical evaluation of accelerator-based neutron sources for the treatment of brain tumors, head and neck cancer, and other malignancies. Reducing the cost.
New study has implications for our understanding of nuclear radiation exposure effects on populations ... “While this dog population is 30 or more generations removed from the one present during ...
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 in minimal entry, exit, or scattered radiation dose to healthy ...
