Stereotactic radiosurgery treats benign or malignant tumors by delivering
high doses of radiation to the central nervous system with great precision,
without an incision.
A sophisticated computer system is used to construct a 3-D model of the
patient's tumor and mark its exact location. Radiation beams are then aimed
at the tumor from several directions, aggressively attacking the tumor, but
sparing surrounding brain tissue from radiation exposure. This ensures
uniform radiation to the tumor and decreases radiation of surrounding normal
tissue.
The Center also performs fractionated stereotactic radiotherapy. During this
procedure, treatment is given in lower doses of radiation over several visits
rather than all at once.
