GAMMA KNIFEŽ SURGERY
KnifeŽ stereotatic units deliver a precise dose of radiation to a small volume
of tissue within the brain. Used for brain tumors, arteriovenous malformations
and brain dysfunctions such as trigeminal neuralgia, the Gamma KnifeŽ offers a
non-invasive alternative for many patients for whom traditional brain surgery
is not an option. Gamma KnifeŽ surgery removes the physical trauma and the
majority of risks associated with conventional surgery. Using preoperative
radiological examinations, such as CT scans, MR scans and angiography, a
treatment plan is developed to provide highly accurate irradiation of
deep-seated targets, using a multitude of collimated beams of ionizing
In a single treatment session, 201 beams of Cobalt-60 gamma radiation are
focused precisely on the lesion. The exposure is brief and only the tissue
being treated receives a significant radiation dose, while the surrounding
tissues receive a minimal or modest dose.
