Gamma Knife radiosurgery can treat brain tumors and
vascular malformations while sparing adjacent healthy,
normal brain tissues. This is due to the ability of the
Gamma Knife to focus a large number of radiation beams
on a precisely defined target volume.
Because of the very rapid fall-off a radiation does
outside the target volume with radiosurgery, the
surrounding brain tissue receives very little radiation
exposure. This extreme localization of radiation does to
within the target volume greatly reduces the risks of
Gamma Knife radiosurgery compared to vocational
radiation treatment or brain surgery. |
