Cobalt therapy is the medical use of gamma rays from the radioisotope cobalt-60 to treat conditions such as cancer.Beginning in the 1950s, cobalt-60 was widely used in external beam radiotherapy (teletherapy) machines, which produced a beam of gamma rays which was directed into the patient's body to kill tumor tissue.
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 ] .
Even earlier than 1940, in the whole North-West India, Bikaner was the only place to provide Radiation Therapy by the deep and superficial X-ray to cancer patients. In pre independent era, cancer treatment by Radium was made available here. The first Tele Cobalt-60 machine for treatment of cancer patients was commissioned in 1965.
Radiation therapy or radiotherapy (RT, RTx, or XRT) is a treatment using ionizing radiation, generally provided as part of cancer therapy to either kill or control the growth of malignant cells. It is normally delivered by a linear particle accelerator .
A Therac-25 had been in operation for six months in Marietta, Georgia at the Kennestone Regional Oncology Center when, on June 3, 1985, applied radiation therapy treatment following a lumpectomy was being performed on 61-year-old woman Katie Yarbrough. She was set to receive a 10-MeV dose of electron therapy to her clavicle. When therapy began ...
The first treatment of a patient using the new source was carried out in London, Ontario, on 27 October 1951. In November 1951, the first Saskatoon patient, a 43-year-old mother of four, was treated for cervical cancer with a carefully calibrated dose of cobalt-60 radiation.
Stereotactic External-Beam radiation Therapy, sometimes called SBRT is now being used to treat Small Cell Lung Cancer, and Sarcomas that have metastasized to the lungs. The high doses used in thoracic SBRT can sometimes cause adverse effects ranging from mild rib fatigue and transient esophagitis , to fatal events such as pneumonitis or hemorrhage.
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.
