Linear Accelerator (LINAC)

Linear accelerator machines have 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. LINAC machines create high-energy radiation that can be targeted to the exact location of a tumor or lesion.

In 1994, Jefferson became the first hospital in the world to possess a LINAC machine used exclusively for stereotactic radiosurgery of the brain. In August 2014, Jefferson launched a new TrueBeam STx Slim with BrainLab Novalis. Currently, Jefferson is proud to be the fourth institution to offer this leading-edge technology in the country.

Increasingly, LINACs are also being used to treat deep-seated arteriovenous malformations (AVMs), sometimes in conjunction with other neurosurgical procedures that shrink the AVMs.

What Does LINAC Treatment Involve?

During a LINAC treatment session, our specialists deliver photon energy beams through a series of "collimators," which focus the radiation. The machine moves on a gantry 360 degrees around the head to provide treatments carefully calculated by the neurosurgeon on the computer. The LINAC's range of motion allows our team to focus on very specific targets that have a variety of shapes and sizes.

If you are receiving multiple treatments, count on at least one hour for your first treatment. Treatment time will vary, depending on a variety of factors, including your diagnosis.
