Stereotactic Radiosurgery - Linear Accelerator (LINAC)
Linear accelerator (LINAC) machines create high-energy radiation that can be targeted to the exact location of a tumor or
lesion. Although LINAC machines are used to treat tumors throughout the body, special modifications are required to use a
LINAC for stereotactic radiosurgery and radiotherapy of the brain. (Jefferson’s Novalis® LINAC machine is equipped for – and
dedicated to – stereotactic radiosurgery and radiotherapy of the brain.)
The LINAC has been proven to be a safe, effective treatment option for patients with inoperable brain tumors in dangerous
locations, such as the optic nerve and brain stem. LINACs are also being used to treat deep-seated arteriovenous malformations
(AVMs, which are tangles of abnormal blood vessels), sometimes in conjunction with other neurosurgical procedures that shrink
the AVMs. The LINAC can be used to deliver both single-dose stereotactic radiosurgery
and multiple-dose stereotactic radiotherapy.
After inputting the patient’s MRI and CAT scan results, medical experts use computer software to develop and implement a treatment
plan. Based on that plan, the LINAC attacks the tumor or lesion with highly targeted radiation. To ensure precision, the patient’s
head is held still by a masking or mouthpiece system. The machine rotates around the patient and makes real-time adjustments
to the surface where the patient lies during treatment.
