The inaugural CyberKnife system was installed at Stanford University in 1991, receiving clearance for clinical investigation by the U.S. Food and Drug Administration (FDA) in 1994. Following extensive clinical research , the FDA granted approval for the treatment of intracranial tumors in 1999 and for tumors throughout the body in 2001.
Radiosurgery is surgery using radiation, [1] that is, the destruction of precisely selected areas of tissue using ionizing radiation rather than excision with a blade. Like other forms of radiation therapy (also called radiotherapy), it is usually used to treat cancer.
The field of radiation therapy began to grow in the early 1900s largely due to the groundbreaking work of Nobel Prize–winning scientist Marie Curie (1867–1934), who discovered the radioactive elements polonium and radium in 1898. This began a new era in medical treatment and research. [119]

The studies are titled, “Prostate CyberKnife Stereotactic Body Radiotherapy: Report on the Early Experience at a Community-based CyberKnife Center” Year 1 and Year 2. [ 6 ] In February 2012, a group of physicians from Mexico City traveled to the U.S. and were trained by the Reno CyberKnife staff to prepare for the arrival of the second ...
By the time the center closed in 1986, the 1,063 female beagles had been exposed to radiation, while many more dogs passed through the facility for breeding and as control subjects. [ 2 ] In the 1990s, the remains of 800 irradiated dogs, their toxic feces, and contaminated gravel were dug up, put in metal drums, and sent to a nuclear disposal ...
FLASH radiotherapy is an emerging form of radiotherapy which delivers a high dose of radiation to the patient in an ultra-short time frame which produces a tumour killing effect comparable to conventional radiotherapy but with less damage to surrounding healthy tissue.
