While the Gamma Knife is dedicated to radiosurgery, many Linacs are built for conventional fractionated radiotherapy and require additional technology and expertise to become dedicated radiosurgery tools. There is not a clear difference in efficacy between these different approaches.
The CyberKnife system is a radiation therapy device manufactured by Accuray. The system is used to deliver radiosurgery for the treatment of benign tumors , malignant tumors and other medical conditions.
Gamma radiation detected in an isopropanol cloud chamber. Gamma (γ) radiation consists of photons with a wavelength less than 3 × 10 −11 m (greater than 10 19 Hz and 41.4 keV). [4] Gamma radiation emission is a nuclear process that occurs to rid an unstable nucleus of excess energy after most nuclear reactions. Both alpha and beta particles ...
A gamma ray, also known as gamma radiation (symbol γ), is a penetrating form of electromagnetic radiation arising from the radioactive decay of atomic nuclei.It consists of the shortest wavelength electromagnetic waves, typically shorter than those of X-rays.
Neutron radiation, alpha radiation, and extremely energetic gamma (> ~20 MeV) can cause nuclear transmutation and induced radioactivity. The relevant mechanisms are neutron activation, alpha absorption, and photodisintegration. A large enough number of transmutations can change macroscopic properties and cause targets to become radioactive ...
The Gamma Knife relied on a stereotactic frame screwed into the patient's skull as an external surrogate to triangulate the location of the subject's tumor; Adler instead wanted to rely on recent medical imaging advancements and internal anatomical structures to guide the beam. Dr. Adler also sought to eliminate the costs to secure and ...
