Gamma knife

Since August 2004, gamma knife radiosurgery is available at the CHUS as a minimally-invasive alternative to traditional open neurosurgical procedures.

The Gamma knife, the gold standard among cranial radiosurgical devices, contains 201 cobalt sources which all focus on a single point, allowing precise delivery of a very high radiation dose to an intracranial target. The Sherbrooke gamma knife was the second in Canada, after Winnipeg, Manitoba. Since then, a gamma knife has also been installed in Toronto.
