Today, both Gamma Knife and Linac radiosurgery programs are commercially available worldwide. 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.
Construction of the Singapore Gamma Knife Centre was funded by the Health Corporation of Singapore (HCS) and the Singapore Technologies Precision Engineering (STPE). The project was the first of its kind in Southeast Asia , and the budget totalled to around ten million dollars.
Stereotactic radiosurgery (SRS) is when doctors use a single or several stereotactic radiation treatments of the brain or spine. Stereotactic body radiation therapy (SBRT) refers to one or several stereotactic radiation treatments with the body, such as the lungs.
In 1985, while working alongside Professor Lars Leksell, Dr. Adler was astonished and inspired with Gamma Knife radiosurgery but saw an opportunity to improve. 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 ...
Cobalt units use radiation from cobalt-60, which emits two gamma rays at energies of 1.17 and 1.33 MeV, a dichromatic beam with an average energy of 1.25 MeV. The role of the cobalt unit has largely been replaced by the linear accelerator, which can generate higher energy radiation.
[29]: 13 [32]: 91 [35] [36] Leksell's radiosurgery system is also used by the Gamma Knife device, and by other neurosurgeons, using linear accelerators, proton beam therapy and neutron capture therapy. Lars Leksell went on to commercialize his inventions by founding Elekta in 1972. [37]
