oncology. [edit on Wikidata] 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.
The history of radiation therapy or radiotherapy can be traced back to experiments made soon after the discovery of X-rays (1895), when it was shown that exposure to radiation produced cutaneous burns. Influenced by electrotherapy and escharotics —the medical application of caustic substances—doctors began using radiation to treat growths ...
1900 – Swedish Dr. Stenbeck cures a skin cancer with small doses of radiation [4] 1920s – Dr. William B. Coley's immunotherapy treatment, regressed tumors in hundreds of cases, the success of Coley's Toxins attracted heavy resistance from his rival and supervisor, Dr. James Ewing, who was an ardent supporter of radiation therapy for cancer.
The Cincinnati Radiation Experiments were a series of total and partial body irradiation tests performed on at least 90 patients with advanced cancer at the Cincinnati General Hospital, now University of Cincinnati Hospital, from 1960 to 1971. Led by radiologist Eugene L. Saenger, the experiments were funded in part by the Defense Atomic ...
8–52. MedlinePlus. 001918. [edit on Wikidata] 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.
8-521. [edit on Wikidata] Orthovoltage X-rays are produced by X-ray tubes operating at voltages in the 100–500 kV range, and therefore the X-rays have a peak energy in the 100–500 keV range. [1] Orthovoltage X-rays are sometimes termed "deep" X-rays (DXR). [2] They cover the upper limit of energies used for diagnostic radiography, and are ...
ICD-9. 92. MeSH. D009683. OPS-301 code. 3-70 - 3-72, 8-53. [edit on Wikidata] Nuclear medicine (nuclear radiology, nucleology), [1][2] is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease.
Image-guided radiation therapy. Image-guided radiation therapy is the process of frequent imaging, during a course of radiation treatment, used to direct the treatment, position the patient, and compare to the pre-therapy imaging from the treatment plan. [1] Immediately prior to, or during, a treatment fraction, the patient is localized in the ...
